Starting from 2012.03, the Linaro toolchains have separated the GCC
support libraries (libstdc++, libgcc_s) from the sysroot itself. So we
no longer have the case where all libraries are inside the sysroot, as
we had for all the previously supported toolchains.
Therefore, we add some logic to detect if such a separate directory is
used for GCC support libraries, and if it's the case, we make sure
that we take into account this directory when creating our own
sysroot, and when copying libraries to the target filesystem.

When an external toolchain is used, it is very likely that it contains
a pre-built version of a gdbserver that has the same version as the
cross-gdb included in the external toolchain. So, we now provide an
option that allows to copy this pre-built gdbserver to the target.
As the location of the gdbserver in the external toolchain is not
standardized, we only support the CodeSourcery and Crosstool-NG
layouts for the moment. Other locations can be added later.

Linaro has just released a new pre-built toolchain, available as a
tarball, which is a pure toolchain (only the C library is
included). This makes this new Linaro 2012.01 toolchain usable in
Buildroot, so let's integrate the support for it.
In addition to simply adding the new external toolchain at the usual
locations, this patch allows need to adapt a few things to support
Linaro toolchains. Most toolchains store their libraries in the "lib/"
or "usr/lib" directories relative to the toolchain. Buildroot
toolchains on the other hand, store the libraries in the
"usr/<target-name>/lib" directory. And the Linaro toolchain has
choosen to use the "lib/<target-name>" directory. Therefore, this
patch adjust:
* The logic to search a particular library when that library needs to
be copied to the target directory
* The logic to deduce the sysroot directory from the libc.a file
location in the toolchain: removing "(usr/?)lib(64?)" is no longer
sufficient, we need to take into account the "lib/<target-name>/"
case.
Since the Linaro toolchain generates code for Cortex-A processors
only, the selection of this toolchain is limited to Cortex-A8 and
Cortex-A9.

The current check for uClibc toolchain was verifying that a

toolchains automatically was added, all the sanity checks on the

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.
Fix it by forcing ELF support.

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.
