[Buildroot] [PATCH 1/3 v3] toolchain/external: add Linaro ARM 2014.11 ARMv7 EABIhf

This toolchain has a kind of history 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, duplicating most
previously existing files in the minimal sysroot, above, and
expending it with the shared libs, the gconv modules and many
other "things";
- 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?).
(reported as https://bugs.linaro.org/show_bug.cgi?id=1417 )
- there's a stray backup file for libstdc++
(reported as https://bugs.linaro.org/show_bug.cgi?id=1418 )
So, add this new toolchain as a replacement for the previous 2014.09
one.
We add three post-extract hooks, one to extract the secondary, sysroot
archive, the second to restore sys/types.h to a useable state, and the
third to remove the backup file.
(Note: we're doing it in three hooks, because the cleanup hook is
different for the AArch64 toolchain, coming soon...)
