The current SSP handling is incomplete.
First we need to build uClibc with SSP support for a complete
"experience".
Second, it doesn't hurt to add -fstack-protector-all to the
CFLAGS/CXXFLAGS since most users would expect buildroot to do this
rather than adding the flags themselves.

It runs out of registers, it fails even in official form
(COMPILE_IN_THUMB_MODE=y) so just build it in ARM mode since EABI
mandates interworking.

uClibc picks the wrong interpreter for MIPS64/n64.
This patch fixes this problem by checking the selected
MIPS ABI instead of the MIPS variant.
The patch has been committed upstream:

With the move of uclibc to package/uclibc, the uclibc-menuconfig target now
depends on uclibc-configure, which brings in the build of
binutils/gcc-initial/mpfr/gmp, causing it to take ages with a clean tree.
Fix it by moving the basic .config mangling to the patch step, and depend
on that for menuconfig instead.
Notice that this is broken for _OVERRIDE_SRCDIR users, just like for
busybox, but as that is presumably a small subset of the buildroot
user base (and these advanced users can just run menuconfig in their
local uClibc tree), so this is considered the lesser evil of the two.
The proposed out-of-tree build series will also cause problems with
this.

This commit adds three patches to uClibc that are needed to make
Thumb2 support work properly:
uclibc-0006-arm-clone-restore-stack-pointer-just-after-return-fr.patch
uclibc-0007-arm-clone.S-Add-missing-IT-instruction-for-Thumb2.patch
uclibc-0008-arm-move-check-for-BX-to-its-own-header.patch
The first one is a necessary dependency of the second one. Both of
those patches have already been merged upstream, after 0.9.33.2. The
third one hasn't been merged upstream yet, but it has already been
submitted a while ago by Yann E. Morin, without receiving attention
from upstream.

Using the newly introduced 'eglibc' package, this commit enables the
option of building a toolchain using the eglibc C library in the
Buildroot toolchain backend.
In details, this commit:
* Creates a choice to select uClibc or eglibc in the Buildroot
toolchain backend (in toolchain/toolchain-buildroot/Config.in), and
removes the fact that the Buildroot toolchain backend forcefully
enables uClibc (toolchain/Config.in).
* Creates a BUILDROOT_LIBC variables, which points to the package
implementing the C library (i.e either 'uclibc' or 'eglibc').
* Modifies the gcc-final and gcc-intermediate makefiles to use the
BUILDROOT_LIBC variable instead of hardcoding the use of uclibc.
* Ensures that TLS support is always enabled when building eglibc.
[Peter: fix commit text to refer to BUILDROOT_LIBC]
