The current check for uClibc toolchain was verifying that a
ld-uClibc.so dynamic loader was present. However, with static-only
uClibc toolchains, this does not work. Instead, we check for an
uClibc-specific header file in the sysroot.

When an external toolchain has multiple variants organized in
sub-directories, Buildroot only copies the selected sysroot and not
all sysroots. In order to make this work, Buildroot creates a symbolic
link of the name of the original selected sysroot to the main sysroot
to trick the compiler so that it finds its libraries at the expected
location.
I.e, if the toolchain as the following organization (example take on
the ARM CodeSourcery toolchain) :
. for ARMv5T
armv4 for ARMv4T
thumb2 for ARMv7-A/Thumb
and ARMv4T is selected, then Buildroot will copy the contents of
armv4t/ from the toolchain into its $(STAGING_DIR) and then create a
$(STAGING_DIR)/armv4t symbolic link to $(STAGING_DIR).
However, our logic to do so only works when there was one directory
level for multilib sysroots. But in the MIPS CodeSourcery toolchain
there are multiple levels. For example, the MIPS16 soft-float
little-endian sysroot variant is in mips16/soft-float/el/ compared to
the main sysroot.
This patch improves our logic to support this case. The logic is a bit
more complicated as we don't want to create a symbolic link to an
absolute path, but a symbolic link to a relative path, because we want
the host/ directory to be relocatable.

The IA32 Sourcery CodeBench toolchain has a relatively special
structure, with the following multilib variants:
* Intel Pentium 4, 32 bits, the multilib variant is in ./ relative to
the main sysroot, with the libraries in the lib/ directory.
* Intel Xeon Nocona, 64 bits, the multilib variant is in ./ relative
to the main sysroot, with the libraries in the lib64/ directory.
* Intel Atom 32 bits, the multilib variant is in atom/ relative to
the main sysroot, with the libraries in the lib/ directory.
* Intel Core 2 64 bits, the multilib variant is in core2/ relative to
the main sysroot, with the libraries in lib64/ directory.
So the first two variants are in the same sysroot, only the name of
the directory for the libraries is different.
Therefore, we introduce a new ARCH_LIB_DIR variable, which contains
either 'lib' or 'lib64'. This variable is defined according to the
location of the libc.a file for the selected multilib variant, and is
then used when copying the libraries to the target and to the staging
directory.
In addition to this, we no longer use the -print-multi-directory to
get the ARCH_SUBDIR, since in the case of the 64 bits variants of this
toolchain, it returns just '64' and not a real path. Instead, we
simply compute the difference between the arch-specific sysroot and
the main sysroot.
We also take that opportunity to expand the documentation on the
meaning of the different variables.

Similar to how we do for target (ee39d53ce3ee (Fix GDB BFD test linking)).
Gdb comes with an embedded copy of libiberty, but binutils also installs
libiberty.a into HOST_DIR. The gdb configure script tries to link against
this one rather than the gdb version when it checks for ELF support.
This may fail if those versions are not compatible, leading to obscure
error messages from gdb at runtime such as:
I'm sorry, Dave, I can't do that. Symbol format `elf32-$ARCH' unknown.

Newer versions of GDB need pthread debugging support if threads are
enabled, which is always the case for glibc but is a configure option
for uClibc.
We have solved this for internal toolchains by selecting the
BR2_PTHREAD_DEBUG option from the GDB selection if needed, but as this
option isn't available when ctng/external toolchains are used, mconf
prints ugly warnings and the build may fail if an external uClibc
toolchain without pthread debugging support is used.
Fix it by introducing 2 more hidden config options:
- BR2_TOOLCHAIN_HAS_THREADS_DEBUG
- BR2_TOOLCHAIN_HAS_THREADS_DEBUG_IF_NEEDED
The first tells us if the toolchain HAS pthreads debugging support,
and is checked by check_uclibc_feature in helper.mk for external uClibc
based toolchains.
The second tells us if the toolchain is ABLE TO provide pthreads debugging
support if threads are enabled, either because it's an internal toolchain
where we can force enable it or an external glibc/eglibc toolchain or
uClibc with the option enabled.
Crosstool-ng forcibly enables this support, so those will always work.
The preconfigured uClibc-based toolchains we have also all enable it.
Finally, show a comment if this isn't the case so the (external toolchain)
user knows why. This is placed outside the choice option, as menuconfig
has a bug where it doesn't show choice selections which only contain
comments.

As a result, if e.g. there is no gcc compiler present on the build system, the

will fail non-gracefully.
This patch makes sure that the DEPENDENCIES_HOST_PREREQ are checked *after* the

The gdb tarballs have been re-released after a GPL compliance
issue was found:
http://sourceware.org/ml/gdb/2011-09/msg00030.html
So all versions were re-packaged.
In the process, an 'a' was appended to the version strings, and
unlike the binutils people, the gdb folks are not inclined in
providing legacy symlinks:
http://sourceware.org/ml/gdb/2011-09/msg00036.html
So, this patch fixes the issue by renaming version strings. It is to be
noted that, although the versions got bumped to include an 'a' at the end,
the directory contained in the tarball is still named after the version
string without the 'a'. For example:
- old version : 6.6
- new version : 6.6a
- tarball name : gdb-6.6a.tar.bz2
- directory name : gdb-6.6/
In fact, it does not pose any problem for buildroot, as the extract process
explicitly mkdirs the directory to extract into, *and* strips the first level
of the tree extracted from the tarball.

Bundled config files have architecture-specific values in them,
which may break if buildroot is configured with another architecture
that does not forcibly set these option.
For example, the bundled config files are for x86_64, and define:
CT_ARCH_TUNE="generic"
This comes from the BR2_GCC_TARGET_TUNE config option (in buildroot) that
is set accordingly to the selected (arch,sub-arch).
But if someone configures buildroot for, say, generic ARM, then the
BR2_GCC_TARGET_TUNE config option is not set, and the crosstool-NG backend
Makefile believes it should not be pushed down to the crosstool-NG config
file.
BUT...
The crosstool-NG backend Makefile can not forcibly push BR2_GCC_TARGET_TUNE
down to the CT-NG config file. If BR2_GCC_TARGET_TUNE is empty, the user can
still set CT_ARCH_TUNE by running ctng-menuconfig.
The backend Makefile already passes such values only if they are set.
In the end, we can't push options as-is to the crosstool-NG config, but we
MUST provide sane bundled config files, which this patch does.

internal toolchain, for toolchains generated by the Crosstool-NG
backend, for Glibc external toolchains and for Uclibc custom external
toolchains. It is left unset by the Blackfin toolchain profile.

Peter on IRC reported some build failures for different targets.
They were of two kinds:
- missing/unknown stack unwinding support
- missing *_chk functions
The first is about configure not being able to automagically determine
if stack unwinding support is available for the target. The second is
about fortified build forgetting to build the fortified functions.
This applies to both glibc and eglibc.
After some discussions on IRC with Jacmet, it appears that we can
safely assume both of the following:
- virtually all targets of buildroot will have stack unwinding support
- we do not care about fortified builds (so far)
So, update the bundled crosstool-NG .config file to saner defaults:
- force unwind support
- disable fortified builds
[Peter: fix 'force non-fortified build' sed invocation]

1.11.3 is the latest stable version, and it has a few improvements
we'll find usefull. For example, it hasa a boolean option for
disabling the {,e}glibc fortified build (instead of requiring us
to shoehorn it in extra cflags.
Update the config files.

Currently, the bundled CT-NG config file has no C library configured.
It is quite complex to add and/or munge options in this case.
Now, with one config file per libc familly, it becomes easier.

The arm-softfloat.patch.conditional patches are no longer in Buildroot
since 9af188d883 (October 2009), which
removed support for gcc 3.x and 4.0.x.

The 0.9.29 version of uClibc can no longer be selected on AVR32 since
December 2009 (b642f7eefb). Therefore,
those two patches are now completely useless.

The recent commit adding the external toolchain wrapper has broken the
support for external toolchain. The check_arm_eabi, check_cplusplus
and check_cross_compiler_exists functions were using TARGET_CC, which
points to the toolchain wrapper, but at the moment those functions are
called, the wrapper hasn't been generated yet.
We fix this by passing to these functions the path to the C or C++
compiler they should use for their tests.

Now that we use a wrapper for external toolchains (and internal ones
default to the correct setting), we no longer need to explicitly pass
sysroot/march/mtune/mabi/floating point mode in TARGET_CFLAGS.

Add a simple toolchain wrapper for external toolchains, which forces the
correct sysroot/march/mtune/floating point options needed to use it
with buildroot.
With this in place the external toolchain behaves similar to the internal
ones, and the special handling can be removed. This also means that the
toolchain is usable outside buildroot without having to pass any special
compiler flags.
Also adjust the downloadable external toolchain support to install under
HOST_DIR so it can be used after the temporary build files are removed.
