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.

 # Template file for a debug utility

 # This will get redefined over and over again for each tool, so don't

 # count on it in the functions below.

 # Small function to print the filename

 # Note that this function gets redefined over and over for each tool

 # It's of no use when building the toolchain proper, but shows all its

 # usefullness when saving the toolchain and building the tarball.

 # You shall not echo anything if you're not enabled!

 # Echo the name of the file, without the extension, below.
