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.

ef0f400c26 Introduce four new ARCH specific variables that CT_DoArchValues can set if they want: 
- CT_ARCH_CC_CORE_EXTRA_CONFIG
  - CT_ARCH_CC_EXTRA_CONFIG
  - CT_ARCH_TARGET_CLFAGS
  - CT_ARCH_TARGET_LDFLAGS
This will hopefully enable architectures to specify specific flags.
PowerPC will need them to introduce SPE (coming RSN).

7131764f9c Remove any reference to libfloat. That has gone once and for all. 
Rationale:
Most of the time, soft-float problems are caused by this sucker of gcc:
it has support for soft float for all of the targets I've tried so far,
but does not activate this code until you dwelve into half a dozen of
files to make it accept to build and link the support code...

So, yes: gcc has soft-float support. And again, yes: gcc is a sucker.

  - update the munging function to accomodate the new config variables

Better handle the case where the sample directory already exist but isn't under revision control, and in case the destination file doesn't exist in the sample directory.

1906cf93f8 Add the full crosstool-NG sources to the new repository of its own. 
You might just say: 'Yeah! crosstool-NG's got its own repo!".
Unfortunately, that's because the previous repo got damaged beyond repair and I had no backup.
That means I'm putting backups in place in the afternoon.
That also means we've lost history... :-(
