cc/gcc: fix cc symlink when executables have an extension

When building a cross-compiler for a host which depends
on file extensions the symlink for cc was not installed correctly

libc/newlib: don't do // downloads

The newlib FTP site does not like // downloads, and quickly
blocks the IP from the downloader.

Override the number of chunks when downloading newlib.

libc/glibc: fix kernel version check

Since we log the test strings, it is no longer possible to call
the CT_Test* functions from sub-functions that print results to
their stdout.

scripts: also prepare include symlink to sysroot/include

scripts: check g++ only for host

g++ is only needed when building additonal libs on the HOST,
so check wheter g++ is available for the HOST compiler only

cc/gcc: use proper host compiler for canadian bare-metal

While compiling a canadian toolchain for host=mingw32, build=linux,
target=m68k-elf the build fails because in this step of the gcc build
the Host compiler is used in this stage with the build-flags for the
build system. This results in an error where the header <sys/wait.h>
cannot be found.
This problem happens at least in the GCC-4.3.x and GCC-4.4.x range.

This is solved by passing the proper compilers on the Make cmd-line

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.

complibs/mpfr: fix extract

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

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
