This is workaround, as more packages require similar tweaks (some
depend on X_Y_Z_or_later config variables either in kconfig, or in
the build scripts.
We should have a CT_CompareVersion, that will apply the default
or per-package method of comparison.

1.0.18 changed the dependencies for the static libraries, notably
in libc/Makefile.in. This resulted in packing a lot of unrelated
stuff into libc.a, including (sic!) a nested .a library and stuff
from other libraries such as libdl. This results in a failure to
statically link with thus created libc.a:
.../libc.a(libdl.os):(.literal+0x74): undefined reference to `_dl_tlsdesc_return'
This was breaking xtensa-*-uclibc sample.

1.0.15 only kept a single LINUXTHREADS option, and renamed it, making it
no longer option-compatible with uClibc.
The option for "1.0.14 or later" version of uClibc-ng is not currently
used; rename it to "1.0.15 or later" and use it to handle newer
uClibc-ng's linuxthreads.
m68k happens to be the only sample using linuxthreads.

In preparation for multilib support, use the same "backend" model that
is already employed by glibc and musl.
Also, the verbosity setting descriptions were swapped. V=2 is actually
less verbose than V=1: V=1 prints full commands, while V=2 prints 'CC
<file> <defines>'.

- Dump CT_LIBC_EXTRA_CC_ARGS: instead, treat CT_LIBC_EXTRA_CFLAGS as
arguments to CC (or they are not applied to .S, for example).
Combine them with multi_flags and CT_TARGET_CFLAGS in proper order.
- Analyze thus combined flags to determine --with-fp/--without-fp.
Don't need to check CT_ARCH_FLOAT - it is reflected in
CT_TARGET_CFLAGS anyway. Check more soft/hard float options defined
on different architectures.
- Drop checking for endianness flags: they are not reflected in
configure arguments in any way, and they're already present in CFLAGS
(either via multi_flags or via CT_TARGET_CFLAGS). Besides,
CT_ARCH_ENDIAN_OPT was actually called CT_ARCH_ENDIAN_CFLAG, so this
was a no-op anyway.

If EXPERIMENTAL is not set, the only choice for version is the set of
released versions - currently, 1.1.14. But this only option is disabled
because it is also marked EXPERIMENTAL; this leaves no available choices
in the configuration.
Marking MUSL as experimental: it seems to have header issues which
prevent, for example, gdbserver from building. musl copied chunks of
ptrace.h code from the kernel into its own headers, which now clash with
Linux kernel headers. Manifests at least on SH4 target.
Also, musl breaks in powerpc builds: GCC balks at it with "unsupported
DEFAULT_LIBC" message. Also, 64-bit powerpc and mips are not supported.
So, until someone figures out the dependencies for musl in config/, mark
it experimental.

The avr-libc project has released version 2.0.0:
http://savannah.nongnu.org/forum/forum.php?forum_id=8460
Apart from changes and bugfixes, this release adds support for gcc 5,
which allows us to build gcc 5 avr toolchains and also to update our avr
sample.
avr-libc 2.0.0 has been build tested both with gcc 4.9.3 and gcc 5.3.0.

GLIBC 2.23 dropped support for pre-v9 SPARC in pthreads. Pass host

We now only support glibc >=2.18
This now enables us to clean up glibc support!
Also, add a comment about glibc 2.20 as the point which glibc no longer
supports not building with pthread.

As per #222, in crosstool-NG >= 1.23.0, we will only support:
[upstream supported gcc versions] - 1
As of this writing, these versions are:
* 5.2.0
* 4.9.3
* 4.8.5 (the -1, since development on 4.8.x is now closed)
I plan to keep 4.8.5 around because of some architectures having issues
with over-optimization or just faulty optimization in the 4.9.x and
possibly newer versions.
I also cleaned up a requirement for glibc to depend on >= gcc-4.6.x for
>= glibc-2.20, but since the lowest gcc we support after this change is
>= 4.8.5, this condition can go away.
Patches for older gcc versions are removed in the next commit.
This closes#222

.. they're needed for the RPC generation in glibc
on both Cygwin and MinGW-w64.
Neither are built on GNU/Linux and iconv is not
built on Darwin.
Two patches for gettext are needed, one so that
-O0 works and one so that static builds can be
made.
They can take a good while to build, so if not
needed for_host or for_build then they are not
built.
