This toolchain has a kind of hstory of its own... ;-(
First released in November 2014, it was completely broken, and Thomas
opened a bug report. Here's the story (for reference):
https://plus.google.com/+ThomasPetazzoni/posts/SjFkrX3ow5M
https://bugs.linaro.org/show_bug.cgi?id=862
since then, the release has been re-done, and the issue reported above
has been fixed. This makes that toolchain almost usable by Buildroot,
with just a few little nits:
- it is available only for x86_64 hosts
- the toolchain is split in three parts:
- the main archive, with the tools and a minimalist sysroot with
just the strictly required stuff (e.g. just the C library and most
libs as static libs, i.e. no shared libs but libc.so)
- a secondary archive, with the complete sysroot , duplicationg most
previously existing files in the minimal sysroot, above
- a tertiary archive, with the 'runtime' content (whatever that
could mean...); that one seems completely unnecessary for
Buildroot.
- the sys/types.h headers from the main sysroot is correct, while the
one from the secondary archive (thus overwriting the main one) is
broken, as it removes the definition of caddr_t (why? WHY?).
So, add this new toolchain with two post-extract hooks, one to extract
the secondary, sysroot archive, the other to restore sys/types.h to a
useable state.

+ Linaro toolchain for the ARM architecture. It uses Linaro
+ GCC 2014.11 (based on gcc 4.9), Linaro GDB 2014.11 (based on
+ GDB 7.8), Linaro glibc 2014.11 (based on glibc2.20), Linaro
+ Binutils 2014.09 (based on 2.24). It generates code that runs
+ on all Cortex-A profile devices, but tuned for the Cortex-A9.
+ The code generated is Thumb 2, with the hard floating point
+ calling convention, and uses the VFPv3-D16 FPU instructions.
