But, until arm support is upstream, we'll switch to Waldemar Brodkorb
version of elf2flt.

Since older GCC versions have been removed, older versions of binutils
are not needed.
This commit removes these older versions.

The gold linker cannot currently be built in a static toolchain build.
This may get fixed in a future version of crosstool-NG.
Also, there is a bit of weirdness here. versions of binutils >= 2.21
have GOLD (BINUTILS_HAS_GOLD), but that doesn't mean it should be used.
For instance, if the architecture is not supported.
So with that, we create a new hidden option: BINUTILS_GOLD_SUPPORT
Which in turn depends on BINUTILS_GOLD_SUPPORTS_ARCH, BINUTILS_HAS_GOLD,
and not STATIC_TOOLCHAIN... then replace anything that previously
depended on BINUTILS_HAS_GOLD with our new BINUTILS_GOLD_SUPPORT option.
This closes#210

As posted on http://www.eglibc.org/
====================
EGLIBC is no longer developed and such goals are now being addressed
directly in GLIBC.
====================
I'm not interested in maintaining build support for unsupported
software.
Older branches of crosstool-ng continue to have eglibc support.
If you find issues with older branches, I'm always open to pull
requests.
Removing eglibc also frees up glibc cleanup and build optimization.

No need to 'select' gold and plugins in versions later
than 2.21, since we inherit them with 2_21_or_later.

Thus spake Niels:
This commit adds support for binutils 2.23.2
http://crosstool-ng.org/hg/crosstool-ng/rev/bc4b36e3df0c
However, in 'config/binutils/binutils.in <http://binutils.in>' the
Kconfig option to select this version of binutils does not automatically
select the symbol 'BINUTILS_2_23_or_later'. This makes gold unavailable
for the latest version of binutils. I'm not sure whether this is on
purpose or not, my impression is that you forgot to add the line "select
BINUTILS_2_23_or_later".
The problem still persists in the latest version in the repository
(032ebcc89c96).

In preparation of adding a new kernel-type, Yann D. came up
with a change in semantic on binutils/gold availability.
So far, it was architectures' responsibility to declare that
they did support binutils/gold or not. It makes much more sense
that binutils/gold declares its own availability depending on
the current architecture; after all, architectures have no way
to know wether gold supports them, while gold does know it.

sstrip has been obsoleted for a while now, as it's still broken
for some archs, and there seems to be no incentive to fix it
upstream. Besides, the space gained with sstrip is marginal at
best.
