- Glibc configure args and tuple need adjustment on SuperH
- Only allow "both endian" and "with CPU" for unspecified arch
variant. May reconsider endianness (was breaking things before
adjusting glibc tuple)
- Retire non-multilib sample, it should be a subset of the
multilib one now.

1. On SuperH, configuring GCC with explicit variant of the CPU
(like "sh4") limits the default set of multilibs to just that CPU
and requires --with-multilib-list to change. Allow for "unspecified"
variant, so that we can defer to GCC to determine the list.
2. Support toolchains with both endiannesses at the same time.
3. Add a SuperH/newlib sample
4. Add more flags processing for uClibc

Must have eabi suffix for GCC to accept it. Also:
- We only have one glibc now, no need to account for eglibc.
- Rename aarch64 samples, eabi suffix does not apply to them
(and ct-ng saveconfig was saving them into a different directory).

- Remove executable permissions and shebangs from the scripts that are
supposed to be invoked only via ct-ng frontent; prepend them with $(bash).

- Install bash completion where Debian (now) expects it
- Update man page to use .\" as the comment delimiter, instead of

Allow cross-gdb and gdbserver. This requires removal of an explicit
check that disables gdbserver on android. However, the comment above
that check refers to exec_elf.h, which has been removed since API level
19. It builds fine with current selection of the sample (21). Only
build-tested, hope someone can give it a try and report back.
We can fine tune the check for GDB but I'll leave it for now.

- libpthread requires iteration over multilibs, unlike the core, it
does not detect and build multilibs by itself.
- Disable parallel builds for mingw-w64 components; until mingw-w64 core
builds clean, I am not trusting it.
- Make the list of tools to build configurable
- Turn on multilib in x86_64 sample.
- Make warnings about tuple less redundant. As in, "one WARN is enough,
no need to shout it three times".
- Messages about various steps/substeps are more aligned with the rest
of the components.
- Use 'make' instead of ${make} to invoke the companion make just built,
if applicable.

Old workaround in 100-gcc.sh stopped working (probably, due to one

GCC does not distinguish the resulting binary by the CFLAGS (e.g. based
on which -march= was given). This means, while it will use the right
libraries for linking, at runtime they are all going to request the same
ld.so path and load the libraries from the same default path.

This follows the trend set by 1*.sh scripts that configure ISL, GMP,
MPFR, CLooG, etc. Building with shared libraries presents all kinds
of problems:
- The shared libraries need to be installed into ${CT_PREFIX_DIR}.
- The binaries linked against companion libs need to have proper
RPATH, or they're looking for shared libs in
.build/${CT_PREFIX}/buildtools/lib.
- All libraries must agree as to whether they're built shared,
static, or both. Otherwise, gettext tries to link in static libncurses.a
into a shared library and fails (since libncurses was compiled without
the -fPIC switch and hence contains relocations that cannot be handled
in a shared library).
So this fixes the current mess. If we decide to re-enable building
the companion libs shared, we should probably make this dependent on
a separate suboption of CT_STATIC_TOOLCHAIN.
Add a config loosely based on one reported in the issue 274.

This enables the resulting toolchaing to be used to build a canadian
cross to x86_64-pc-linux-gnu target. Unmark that sample as broken,
it now builds successfully.
It is likely that it is affected by issue #483, too - I see the
resulting gcc executable has a DLL dependency on libiconv-2.dll,
which is only installed into .build/.../buildtools. This will be
investigated/fixed separately.

To build uClibc correctly we need correct endianness selected in the
crosstool-NG. Xtensa cores may be little- or big-endian, but this
property is static. The toolchain knows the core endianness and doesn't
need options to select it.
Enable ARCH_SUPPORTS_BOTH_ENDIAN and select LE by default. Specify empty
CT_ARCH_ENDIAN_CFLAG so that -m{big,little}-endian don't get added to
the TARGET_CFLAGS, as it's not supported by gcc. Specify empty
CT_ARCH_ENDIAN_LDFLAG so that -EB/-EL don't get added to the
TARGET_LDFLAGS as they are ignored. Select big-endian in the example
xtensa-unknown-linux-uclibc configuration.
This fixes uClibc toolchain build for little-endian cores.

This change adds a powerpc64le-unknown-linux-gnu sample that can be used
to quickly create a little-endian tool-chain for powerpc64
architecture. This sample is based on the earlier work done by "Yann
E. MORIN" to add support for powerpc64 tool chain and implementing the
power64-unknown-linux-gnu sample. The existing sample however generates
a big-endian tool chain by default.

With avr-libc 2.0.0 released, we no longer need to force gcc 4.9.x for
the avr toolchain. So, remove the gcc version constraint and allow it to
follow the default gcc version. There is also no need to force companion
libraries' versions anymore.
The 'experimental' flag was also removed from the description as it
seems to be following upstream development now.

I couldn't get this sample to build. I tried rolling ct-ng back to 1.22
and back to the commit that introduced it, to no avail. Not sure if it
ever built on my machine.
The first problem is the failure to build binutils/gold because of the
missing <pthread.h> in mingw. However, even if CT_BINUTILS_GOLD_THREADS
option is unset, the build dies in configure of the pass-1 of the core CC.
The config.log states that it failed to link with libmpfr.a, which has
a lot of undefined references to symbols like '__imp___iob_func'.
Googling shows that these symbols are some dark Cygwin/MinGW magic and I
do not have the knowledge of these arcana. Let some other MinGWizard fix
it another day.

There is invalid assembly in dmalloc for PowerPC. The issue is that
'stw' expects a memory operand, and =g constraint allows both registers
and memory. Newer GCC tends to choose register even at -O0, resulting in
invalid assembly. Instead, force a register constraint in 'mflr' and let
GCC decide if it wants to store it into memory at all.
Reported this upstream.
