Some architectures, like arc and blackfin set CROSS_COMPILE to a default
if it is not set on the command-line.
Since we are building the cross-compiler, we need to ALWAYS set
CROSS_COMPILE, since building/checking headers is done after the GCC
PASS1 step.

This is a weird artifact from when mips64 was first introduced to ct-ng
and was never removed from experimental.
If you have problems building a mips64 toolchain, please report on the
mailing list or on github issues.

This change, as per #222, reduces the number of supported releases of
gcc to the latest branch releases.
I noticed while doing this work that gcc-4.5.4 was never added, so I
moved patches for gcc-4.5.3 to 4.5.4 and updated the
bfin-unknown-linux-uclibc example. Also, 120-siginfo.patch was fixed
upstream in the 4.5.4 release, so this patch is omitted.
I also bumped the avr sample to 4.9.3 from 4.9.2.
With the addition of gcc-5.x, the gcc release team now releases the
major.minor.0 versions, while updates to the branch are available in
svn/git. We'll address that when we get to issue #219. This change just
removes CC_GCC_5_1 and moves CC_GCC_5_2 to CC_GCC_5, and removes
CC_GCC_5_1_or_later and moves CC_GCC_5_2_or_later to CC_GCC_5_or_later.
This is the first of two part changes, as mentioned in #222.
This change is slated for release in 1.22.0. The next change will be
slated for 1.23.0, and will limit gcc versions to what is on
https://gcc.gnu.org under "Release Series and Status", which is
currently 4.9.3 and 5.2.0, although I will also support the previous
supported version. In this example that would be 4.8.5.
Last, but not least, this change also retires AVR32 support.

Provides a simpler alternative to editing config to enable
CT_ONLY_DOWNLOAD, doing ct-ng build and then restoring .config.

Building cross-gdb in canadian cross requires expat/ncurses for the
host. Currently, 300-gdb.sh only builds expat/ncurses for the target
(for native-gdb). For cross-gdb on regular cross (build==host), expat
and ncurses are expected to be provided by the host.
There are two approaches possible:
- If building for canadian cross, build expat/ncurses for cross-gdb
just as the native-gdb does.
- Promote expat/ncurses to first class citizens and build them as
companion libs during the build of the build-to-host toolchain.
I am leaning towards the latter approach - it would also allow to
specify the versions for expat/ncurses rather than have them hardcoded
in 300-gdb.sh - but would appreciate feedback.

Having *.la in the installation directory breaks ltrace: in ltrace,
libtool somehow considers libsupc++ to be an "accessory library" and
does not add -lsupc++ to the link flags. Neither Ubuntu, nor RedHat
include *.la files into their packages for libstdc++.

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

The issue with this sample is that the sh4-* targets in GCC do not
implement __builtin_trap() function. Starting with release 5.1,
GCC inserts abort() calls where NULL pointers are dereferenced. The
elf/dl-conflict.c in glibc is one such place: it calls elf_machine_rela
with NULL `sym' pointer. This causes an undefined `abort' symbol to
appear in the object file and as a result, pulls in some files during
the linking of the dynamic loader that are not supposed to. Eventually,
it results in link error due to multiple definitions of _itoa and some
other symbols.
The right fix would be to implement __builtin_trap() for sh4 in GCC.
A workaround would be adding -fno-delete-null-pointer-checks to
CFLAGS-dl-conflict.c in elf/Makefile. Until either of these happens,
though, pin the GCC version to 4.9.3 - the last that did not generate
`abort' calls. Note that the version where GCC started to generate
`abort' calls is apparently different for different architectures;
the issue in [1] was reported against GCC 4.9.
References:
[1] https://www.sourceware.org/ml/libc-alpha/2014-10/msg00807.html
(similar issue on HP-PA which was resolved by implementing
__builtin_trap)
Options were renamed. However, matching current option names result
in a compile error for strfmon_l.o in glibc: GCC 4.6 detects an
unitialized variable in its own va_arg() implementation. Likely,
an older GLIBC was used when this sample was submitted - which did
not provide -Werror in CFLAGS.
Thus, use most recent GCC (5.2.0) and revert GLIBC_FORCE_UNWIND to
its default value, 'y' (as forced unwind is required with this version).
- Incompatible ISL/CLooG were requested by config after newer releases
of both were brought in.
- Consistency with other samples: save tarballs (which will avoid
downloading them each time from Travis), extra logging.
This should ideally be upstreamed to uclibc maintainers, but with the
last release more than 3 years ago, I wouldn't hold my breath for a
fix being released any time soon.
