656dae57eb cc/gcc: baremetal requires a two-pass process 
Here, we implement a highly ugly hack. I'm not proud of that one...

To build the libstdc++ library, the compiler requires the C library. In
case we build for non-baremetal, this is normally handled by the final
step, later.

But in the case of bare-metal, we never go through the final step (because
it does not work, and it seems complex enough to make it work), so the
baremetal compilers are issued out of the core step.

9c6c090d7b 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

93042972a8 cc/gcc: fix thread-less final gcc build 
If threads are disabled in libc, we don't want to enable them in the
final compiler. Doing so pass the configure stage, but fails latter on
a missing <pthread.h>.

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

355586027b Add support for building toolchains with gcc-4.4 snapshots. 
Initial patch by Dmitry PLOTNIKOV: http://sourceware.org/ml/crossgcc/2009-03/msg00053.html
  It [the toolchain] uses current ct-ng (nightly snapshot 20090324, latest
  release 1.3.2 work also), glibc 2.9 (from CVS), binutils 2.19 and latest
  snapshot of GCC 4.4.0 (as of March 20, 2009).

  We have successfully built linux kernel 2.6.29 and a lot of other stuff
  with this toolchain.

  Here's the patch that adds GCC 4.4.0 to the ct-ng menu and enables it to
  download a 4.4.0 snapshot from ftp.

Patch was adpated by me, mostly to better fit the configuration layout.

- it is unworkable to have CT_ExtactAndPAtch cope with all those silly glibc addons:
  - they can have 'short' (as 'ports') or 'long' (as glibc-ports-2.7) names
  - patches are against eithe the short or long name, but non-uniformly use one or the other
  - it is the reposibility of the component (glibc in this case) to handle corner cases such as those
- update all components to use the new functions

5c48279f0f Make a relative symlink from ${CT_TARGET}-cc to ${CT_TARGET}-gcc. 
This helps those who want to relocate their toolchains later.

6731142c39 Better handle the second pass core gcc build, differentiating between gcc prior to 4.3 with gcc from 4.3. 
Simplify detecting wether gcc is 4.3 and later, or older than 4.3 (we already know from .config).

799672a641 Introduce a new EXPERIMENTAL feature: BARE_METAL. 
This should ultimately llow to build bare-metal compilers, for targets that have no kernel and no C library.
Move the C library build script to their own sub-directory; introduce an empty build script for bare-metal.
Move the compiler build script to its own sub-directory.
Move the kernel build script to its own sub-directory; introduce an empty build script for bare-metal.
Update the ARM target tuples to enable bare-metal targets.
Add two ARM bare-metal samples.
Add latest Linux kernel versions.
