If CDPATH is set in the environment, cd <dir> will print the absolute path
of <dir>, causing various trouble (The most critical being BASE_DIR ending
up as <path> <path> which breaks basically everything).
Fix it by clearing CDPATH. Notice that export doesn't affect the environment
of $(shell ..) calls, so explicitly throw away any output from cd in the
BASE_DIR shell call.

The config cache might contain invalid values when .config is changed
(E.G. when adding/removing libraries), so drop it so config checks are
rerun for new packages (existing package still won't be rebuilt).

As discussed on the list, fixup the *clean targets, so we now have:
clean: remove all generated files (E.G. everything in output/)
distclean: same as clean, but also remove the kconfig build and .config
Also tweak 'make help' output to match. This also merges the two
different clean / distclean targets we had depending on if there was
a .config present or not (most variables are not defined for !.config
case, so E.G. the clean target ends up being a noop).

As discussed earlier on the mailing list. It simplifies code, gives more
sensible error message on typos and makes the defconfigs easier to find

Furthermore, update documentation to match.

E.G. handy for keeping your current toolchain config while testing

In the output directory, we now have
- build/ where all the packages are built
- images/ where the final kernel and rootfs images are stored
- staging/ the staging directory (containing the development files
and libraries compiled for the target)
- target/ which contains the target root filesystem
- host/ which contains all the host programs
- stamps/ which contains the stamps files
Therefore, the build_ARCH and toolchain_build_ARCH have been
removed. People willing to use the same Buildroot sources to compile
for different architectures are invited to use the O= command line
option for out-of-tree compilation.

This can be achieved by adding a new target in target/device/, and I
will later propose a mechanism to add external boards and packages, so
that our users not willing to get their target-specific or
package-specific things merged can keep them cleanly separated from
Buildroot tree.

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,
package/customize/customize.mk,
package/linux-fusion/linux-fusion.mk,
package/ltp-testsuite/ltp-testsuite.mk,
package/nfs-utils/nfs-utils.mk,
target/cpio/cpioroot.mk,
target/cramfs/cramfs.mk,
target/device/Atmel/DataFlashBoot/DataflashBoot.mk,

target/romfs/romfs.mk,
target/squashfs/squashfsroot.mk,
target/tar/tarroot.mk,
target/ubifs/ubifsroot.mk
- Replace PROJECT_BUILD_DIR by BUILD_DIR
* target/device/Config.in
- Do not include project/Config.in anymore
* target/linux/Makefile.in.advanced
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Store the stamps file in $(STAMP_DIR) instead of
$(PROJECT_BUILD_DIR)/autotools-stamps
* target/u-boot/Makefile.in
- Replace PROJECT_BUILD_DIR by BUILD_DIR
- Remove $(PROJECT) from the U-Boot target binary name
- Remove the insertion in the configuration of the project name as
the hostname
- The u-boot-autoscript target now generates
$(U_BOOT_AUTOSCRIPT).img instead of
$(U_BOOT_AUTOSCRIPT).$(PROJECT)
* toolchain/gcc/gcc-uclibc-3.x.mk
toolchain/gcc/gcc-uclibc-4.x.mk
- Move the stamps files to $(STAMP_DIR)

Define a qstrip function that strips double quotes and then
whitespaces around a given string. This is a very commonly needed
thing, and having a function allows to remove a large quantity of
hand-written definitions, followed by a dummy comment to make text
editors not crazy because of the unmatching double quote.

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.
