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.

As suggested by Arnout Vandecappelle, move toolchain/dependencies to
support/dependencies, as it really is not toolchain-specific anymore.

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.
Fix it by forcing ELF support.

Add the ability for buildroot to build an SPE ABI enabled toolchain.
This is mandatory for e500v1/v2 cores since they don't support classic
FPU mode as the e500mc does.
Useful for Freescale's PowerQUICC III and single/dual-core QorIQ
line of processors.
The new TARGET_ABI variable is used rather than TARGET_CFLAGS for
uclibc's UCLIBC_EXTRA_CFLAGS to avoid breakish CFLAGS leaking in, a
good example being -mthumb for ARM.

Most of the extract tools (gzip/bzip/..) we already check for explicitly
in dependencies.sh (as they are used outside GENTARGETS), but not for
xzcat.
The .xz format is used fairly rarely, and it is likely to not be available
on build hosts, so an explicit (hardcoded) check for it isn't optimal.
Instead, add the inflate tools used to DL_TOOLS_DEPENDENCIES, similar to
how we do it for svn/git/bzr/...

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.

Currently, the dependencies target (that runs dependencies.sh) depends on
DEPENDENCIES_HOST_PREREQ. This means that the dependencies listed in
DEPENDENCIES_HOST_PREREQ (currently host-sstrip if sstrip is selected) are
built *before* the dependencies.sh script is run.
As a result, if e.g. there is no gcc compiler present on the build system, the
dependencies in DEPENDENCIES_HOST_PREREQ will fail to build, and buildroot
will fail non-gracefully.
This patch makes sure that the DEPENDENCIES_HOST_PREREQ are checked *after* the
dependencies.sh script, so that any problem in the build system is reported in
a clean way by dependencies.sh.
