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.
