The DODEBUG configuration option in uClibc is broken, even for widely
used architectures like ARM. Therefore, any Buildroot configuration
that has BR2_ENABLE_DEBUG enabled and uses uClibc with the internal
toolchain backend will fail, with an error like:
http://autobuild.buildroot.net/results/d34/d34238c209cf2ef63371a598ab9218165c90f864/build-end.log
This error was also reported recently by a Buildroot user.

This commit refactors how Stack Smashing Protection support is handled
in Buildroot:
*) It turns the BR2_TOOLCHAIN_BUILDROOT_USE_SSP option into an option
that only enables the SSP support in uClibc, when using the internal
toolchain backend.
*) It adds an hidden BR2_TOOLCHAIN_HAS_SSP option that gets enabled
when the toolchain has SSP support. Here we have the usual dance:
glibc/eglibc in internal/external backend always select this
option, in the case of uClibc/internal, it gets selected when
BR2_TOOLCHAIN_BUILDROOT_USE_SSP is enabled, in the case of
uClibc/external, there is a new configuration option that the user
must select (or not) depending on whether the toolchain has SSP
support.
*) It adds a new options BR2_ENABLE_SSP in the "Build options" menu,
to enable the usage of SSP support, by adding
-fstack-protector-all to the CFLAGS.

When NPTL support was introduced, gcc required a three stages build
process. Since gcc 4.7, this is no longer necessary, and it is
possible to get back to a two stages build process. This patch takes
advantage of this, by doing a two stages build process when possible.
We introduce a few hidden kconfig options:
* BR2_GCC_VERSION_NEEDS_THREE_STAGE_BUILD, which is set by the gcc
Config.in logic to indicate that the compiler might need a three
stages build. Currently, all versions prior to 4.7.x are selecting
this kconfig option.
* BR2_TOOLCHAIN_LIBC_NEEDS_THREE_STAGE_BUILD, which indicates whether
the C library might need a three stages build. This is the case for
eglibc, and uClibc when NPTL is enabled.
* BR2_TOOLCHAIN_NEEDS_THREE_STAGE_BUILD finally is enabled when both
of the previous options are enabled. It indicates that a three
stages build is actually needed.
In addition to those options, the uClibc/gcc build logic is changed to
use only a two stages build process when possible.

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.

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.
