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.

20 gcc is the full-blown GNU compiler. This is what most people will choose.
22 gcc supports many languages, a powerful code parser, optimised binary
23 output, and lots of other features.

135 Enter here a comma-separated list of languages that you know your compiler
136 supports, besides those listed above.
138 Eg. gcc-4.1+ has a toy programming language, treelang. As it is not usefull
139 in real life, it is not available in the selection above.
