cc/gcc: allow building a canadian bare-metal compiler

Previous addition of the canadian cross compiler did not allow
to build a baremetal only variant, no reason why this is not
allowed

libc/newlib: the m68k processor does not like unaligned

Disable unaligned access at least for mcpu32, m68010 and m68020.
These processors certainly do not like unaligned accesses.

cc/gcc: add 4.5.0

cc/gcc: add support for 4.5.0 or later versions

starting with 4.5.0, gcc requires libelf.

complibs/libelf: remove old versions

Those old versions are not suitable for use by gcc.

complibs/libelf: enable the host build

Host libelf is required by gcc-4.5.0

complibs/libelf: build target libelf in its own directory

debug/gdb: remove insight

Insight seems to be very slow to follow up on mainstreram gdb.
Latest snapshots are more than 6 months old.

Moreover, I don't have time to maintain insight support in crosstool-NG;
and, because I don't use it, I am unable to find any breakage.

debug/gdb: reorder options in the menuconfig

debug/gdb: allow static build with complibs

It is now possible to built static versions of the companion libraries,
so we can now build a static cross-gdb using the complibs.

scripts: don't print the build system guess warning

complibs/gmp: mark 5.0.1 as being experimental

MPFR can't cope with GMP > 4.x.y so hide it behind EXPERIMENTAL
until we fix MPFR

samples: add Blackfin sample

Add basic support for the Blackfin architecture

For uClibc, the name of the Blackfin architecture is 'bfin'. Actually,
the naming of the architecture is quite messy: for toolchain tuples
and uClibc, it's bfin, but for the kernel, it's blackfin. We've
arbitraly choosen to name it "blackfin" in Crosstool-NG.

Add Blackfin-related uClibc patch to fix a build failure related to
fork() being used in unistd/daemon.c.

Yann E. MORIN:
Apply the patch to the kernel/linux build script to use 'linux'
in the noMMU tuples. See:
http://sourceware.org/ml/crossgcc/2010-04/msg00010.html

scripts/functions: log the test strings

scripts/functions: compress with gzip level 3, as stated in the documentation

Thanks to Bruno Tarquini <btarquini@gmail.com> for the report.

scripts/functions: add a save/restore handler

Saving and restoring the steps requires saving/restoring multiple
directories. Depending on the configuration, some may not exist.

Add a wrapper that checks before creating/extracting the tarballs.

scripts/functions: fix CT_Patch again

Merge.

Revert 3ea4e6f7b85f: Force autoreconf for mpfr

It breaks on my machine. Revert until we find the exact cause leading to
the initial patch, and we come up with a patch that properly fixes it.

scripts/functions: make CT_Patch dumber

It is the responsibility of the caller to split the package name from
its version. It already knows that.

libc/newlib: only compute version string, not full filename

debug/gdb: remove snapshot version

cc/gcc: add bugurl and compiler version to core gcc compiler

When building for bare-metal the core-gcc compiler is delivered
as final compiler, so the version info and bugurl is useful
in the core compiler as well.

complibs: save directory with static complibs for stop/restart

complibs: don't install in toolchain dir when built as static

complibs: allow either static or shared build

complibs: build static libraries

config: replace COMP_LIBS with COMPLIBS

complibs/mpfr: fix extract

With MPFR 2.4.2, autoreconf needs to be run as well.

scripts: add script to publish patches

This script creates the patches for an existing version.

Re-enable the FD_PIC ELF configuration option

Blackfin uses FD_PIC ELF format to provide shared libraries on a
non-MMU architecture.

Fix the uClibc clean-up-O_CLOEXEC-handling patch

In the Blackfin case (untested until now), this patch was lacking a
leading / at the end of a comment.

If a list-file is used, then each library in the file will be handled

already present, just avoid doing the job twice).

cc/gcc: fix thread-less final gcc build

If threads are disabled in libc, we don't want to enable them in the

a missing <pthread.h>.

Moreover, we don't want to build libgomp if threads are disabled; its
configure script would fails anyway.

config: allow libc selection in backend mode

In backend mode, allow the upper-layer build system to force the
C library selection.

config: do not force setting kernel and arch

In backend mode, only enforce the arch and/or kernel selection if the
upper-layer build system effectively forces the selection.

scripts: misc help and auto-complete fixes

- don't list samples in the main help screen
- improve the samples listing in list-samples
- don't document the 'config' action, it's long dead

Always enclose the sourced file between double-quotes (purely for
consistency; enclosing or not are both allowed by the kconfig language).

config: move backend-related options to their own file

config: hide arch and kernel selection when used as a backend

When used as a backend, it is the responsibility of the upper-layer build
system to set the target architecture and kernel.

config: hide options to debug crosstool-NG when a backend

When used as a backend, it does not make sense to debug crosstool-NG,
so hide the option.

config: hide more config options when a backend

Hide the prompts for some behavioral options, for which the upper-layer build
system is responsible for:
- parallel jobs and maximum load
- use pipes
- use custom shell
