When sstrip is selected it tries to strip kernel modules too.
Unfortunately this fails with a "unrecognized program segment header
size" error thus interrupting the build process.
We introduce a new $(KSTRIPCMD) strip command for this, being a regular
strip when sstrip is selected and an empty stub when not stripping.
At the same time get rid of the REMOVE_SECTION_* variables, as they are
only used once.

Ensure host packages (dependencies of target packages) are also handled
by make source / make external-deps.
This has to be done a explicitly, as we don't list these in Kconfig,
and hence also not in a variable like TARGETS, so instead we have to
look at the <PKG>_DEPENDENCIES variables for each enabled package and
extract the host packages from there.
Host packages can in turn also have dependencies, so we have to follow
those as well. Ideally this should be done recursively, but as that's
pretty hard to do in make, it is limited to 1 level for now.
Finally, host packages share source files with target packages, so
pipe output of make external-deps through sort -u to ensure duplicates
are removed.

The configuration cache shared between packages, while being in
principle a nice idea to speed-up the configuration of packages by
avoiding repetitive identical checks, turned out to be unreliable due
to the subtle differences between similar but not identical checks in
different packages. After spending some time trying to fix those, we
concluded that supporting the shared configuration cache is definitely
too hard and too unreliable, and that we'd better get rid of it
altogether.
This patch therefore removes the shared configuration cache

If building out-of-tree, add a Makefile wrapper that calls-out to the real
Makefile with proper args.
Avoids having to pass -C and O= every time we call make.
This is highly inspired from how the Linux kernel does it, and portions of
it have been used. We can't use exactly the same implementation as the
kernel does, because:
- the script writing the wrapper has been expunged of the few lines
that were too kernel-related: in buildroot we do not need the version
string in the wrapper, and we do not have a patchlevel version;
- "in-tree build" does not have the same meaning for the kernel and for
buildroot: for the kernel, $(O) point to the $(TOPDIR), while for
buildroot $(O) points to $(TOPDIR)/output.

The previous commit has removed calls to conf_write_autoconf(), which
is the function that generates the KCONFIG_AUTOCONF,
KCONFIG_AUTOHEADER, KCONFIG_TRISTATE files and the split config (with
one file per config item). Therefore, those things were not generated
anymore before the build.
In order to get them generated before the build, we use the same
mechanism as the kernel: run a silentoldconfig when the .config file
is newer than the KCONFIG_AUTOCONF file.
In Buildroot, all those elements are not really used today, except the
split config which is used a little bit in the toolchain build, in a
try to make sure the toolchain gets rebuilt properly when the
configuration changes. It does not seem that this work has been
completed.
However, as we want to keep the same behaviour as previously, we have
to generate all those elements before starting the build.

Our kconfig-to-buildroot2.patch hasn't been kept up to date with all
the changes made into package/config, and a single patch wasn't very
practical to maintain all our changes. Therefore, this commit adds a
package/config/patches directory, which contains a Quilt series of
patches that correspond to our modifications to the kconfig mechanism.
The huge kconfig-to-buildroot2.patch has been split into 16 smaller
patches. The purpose of some of the modifications has been clearly
identified, while some others were not identified.
The 16 patches together do match exactly the old
kconfig-to-buildroot2.patch. We have been very careful in making sure
that we wouldn't loose any of our modifications.
The only modifications made are :
* Instead of renaming the kernel Makefile to Makefile.kconfig and
naming the Buildroot Makefile just 'Makefile', we instead keep the
original package/config/Makefile from the kernel
scripts/kconfig/Makefile and name the Buildroot Makefile
package/config/Makefile.br. The main Buildroot Makefile is modified
accordingly.
* The documentation README.buildroot2 is updated to explain how to
upgrade to a newer version of scripts/kconfig.
* The kconfig-language.txt documentation is removed, as anybody can
easily find it in the kernel sources so there's no need to
duplicate it here.

- prefer using positive checks, a-la:

- have the toolchain_buildroot case always appear first
- gettext is handled differently, because we want to add an option

The "project" feature was designed to allow to several projects to be
built inside the same Buildroot source tree and allowing the toolchain
and non-configurable packages to be shared between the different
projects on the same architecture. While being interesting in theory,
this feature adds a level of complexity to Buildroot, both from an
user perspective and from a developer perspective, while one of the
main Buildroot strengh is to be simple. Moreover, this feature is only
seldomly used by our users.
From a user-level perspective, this for example allows to remove the
project_build_ARCH directory, which was very confusing. The
autotools-stamps directory is also removed, since these stamps are
back at their normal location.
Description of the changes involved :
* project/, directory removed
* Makefile
- Don't include project/Makefile.in and project/project.mk anymore
- Grab a copy of the contents of project/Makefile.in at the
location it was imported, but remove the definition related to
PROJECT_BUILD_DIR. The TARGET_DIR is now in
$(BUILD_DIR)/target_dir
- Remove the creation/removal of the $(PROJECT_BUILD_DIR) and
$(PROJECT_BUILD_DIR)/autotools-stamps directories
- Don't make world depends on target-host-info. This target was
defined by project/project.mk to customize /etc/issue,
/etc/hostname and create /etc/br-version depending on the
project definitions. We can of course imagine re-adding such a
feature later.
- Replace PROJECT_BUILD_DIR by BUILD_DIR everywhere
- Remove the update, log and lognr.$(PROJECT) target, they were
specific to the project feature.
* package/Makefile.autotools.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
- Move the INSTALL_TARGET and HOOK_POST_INSTALL stamps to the same
directory as the other stamps (i.e, in the package directory).
* package/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR for the location of the
configure cache
* package/at/at.mk,
package/busybox/busybox.mk,
package/busybox/initramfs.mk,

The find command syntax is incorrect when deleting CVS and .svn directories
from the target filesystem, which prevent CVS directories from being
deleted.
It's useful to delete these dirs because users of buildroot often import
buildroot into CVS or Subversion.

It involved:
* Modifying the top-level Makefile to create the xconfig target, and
the $(CONFIG)/qconf target to compile the qconf utility
* Modifying the package/config/Makefile magic so that C++ files and
binaries gets linked properly, re-using the
package/config/Makefile.kconfig logic inherited from the kernel
* Hacking a little bit package/config/Makefile.kconfig in a way
similar to the modifications done for the mconf (menuconfig
interface)

The config help text says it all:
Specify a script to be run after the build has finished and before
the BR2 starts packing the files into selected packages.
This gives users the oportunity to do board-specific cleanups,
add-ons and the like, so the generated files can be used directly
without further processing.
The script is called with the target directory name as first and
only argument. Make sure the exit code of that script is 0,
otherwise make will stop after calling it.

Remove toolchain build dir, and don't try to remove the non-existing include
dir. Also don't explicitly remove the kernel image located in binaries as
we're already removing that dir.
Add BR2_ENABLE_LOCALE_PURGE / BR2_ENABLE_LOCALE_WHITELIST options to
remove unwanted locales from the target rootfs. Handy for stuff like
the gtk stack, which comes with ~25 MB locales.
Works similar to localepurge in Debian, E.G. you provide a white list
of wanted locales, and everything else is removed.
Move stamp (dependency) files outside the (version specific) source
directories, so other packages can hardcode dependencies on them instead
of having to use <PACKAGE>_VERSION variables.
This is important as the variables in the make rules are evaluated when
the rules is seen, which might be before the dependent makefile is parsed
(and hence <PACKAGE>_VERSION variable is known, screwing up stuff.
The downside of this is that the package isn't automatically rebuilt
when the version changes (E.G. by a svn update) and you now also have to
remove the stamp files next to $(BUILD_DIR)/<PACKAGE>-* to force a rebuild.
I often find myself forgetting what those targets were called, and I imagine
others may not even be aware of their existence.

This patch will add a rule to top level Makefile to depend on the
$(PROJECT_BUILD_DIR)/autotools-stamps as a required directory. Hence it will be
generated if missing in stead of made when the $(PROJECT_BUILD_DIR)/.root rule
is triggered.

This patch will create the autotools-stamps directory early in the build
process, thus making it possible for non Makefile.autotools.in packages to use
this directory to hold stamp files.

HOST_GLIB is set to the path that contains the host glib tool set and is
used when building packages using glib. The buildroot top level Makefile
sets HOST_GLIB using which to find the path where glib-genmarshal is
located.
The problem is that a cross compiled version of glib-genmarshal is also
put in the build_ARCH/staging_dir/usr/bin directory when the package
libglib2 is built. This cross compiled version will typically not run on
the host system.
Fix it by ignoring staging_dir in the which output.
Closes#5934
jacmet: fixed to work correctly if it's only found in staging_dir.
Improve external toolchain support
* Do not put kernel-headers in the dependencies of BASE_TARGETS in
the case where BR2_TOOLCHAIN_SOURCE is not y. The kernel headers
are already supposed to be part of the external toolchain, so
there's no need to download, extract and install them.
* In the configuration system, don't display the kernel headers
version selection list when an external toolchain is selected. This
is implemented by moving the source
"toolchain/kernel-headers/Config.in" inside the if
BR2_TOOLCHAIN_SOURCE in toolchain/Config.in.2.
* Change the description and help message of the BR2_LARGEFILE,
BR2_INET_IPV6, BR2_INET_RPC, and BR2_SOFT_FLOAT option in
toolchain/external-toolchain/Config.in. In the case of an external
toolchain, the semantic of these options is not to enable large
file support, IPV6 or RPC (since the toolchain is already compiled,
it has been decided previously). Their semantic is to let Buildroot
know about the characteristics of the external toolchain being
used.
As an improvement, we could guess these values automatically:
- for BR2_LARGEFILE, look at the value of __UCLIBC_HAS_LFS__ in
bits/uClibc_config.h in the libc headers directory.
- for BR2_INET_RPC, look at the value of __UCLIBC_HAS_RPC__ in the
same file
- for BR2_INET_IPV6, look at the value of __UCLIBC_HAS_IPV6__ in
the same file
- for BR2_SOFT_FLOAT, look at the output of $(CC) -v 2>&1 | grep
-- "--with-float=soft"
But I'm not sure how this would be possible, since these values are
used at configuration-time by other configuration options, not only
at build time.

make "make clean" remove the .root stamp, so that everything will
be reinstalled properly on a subsequent build. (bug id 4304)
Also remove new autotools-stamps directory.
The MAKELEVEL test is not that robust; It fails with the recent log
support or if buildroot is driven from an external Makefile.
Rework it to instead detect source-check/external-deps by the fact that
they set SPIDER.
Mark empty directories in target skeletons with .empty files
and remove them while copying to target (like it's already done for
svn and cvs files) to better support version control system which don't
handle empty directories (E.G. git-svn).
Will need to try to copy eventual pre-existing project-specific deps back
to package/config in order not to mess up the corresponding timestamps (to avoid superfluous rebuilds)..
