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.

      libelf lets you read, modify or create ELF files in an

      architecture-independent way.

      libelf is BROKEN! If you manage to make it actually _work_,

      please be so kind as to tell me. (By working, I mean it is

      useable at least by ltrace.) Thank you!
