b8e64a0c08 avr-libc: add support for avr-libc C library
This commit adds support for the avr-libc C library.
According to the project page at http://www.nongnu.org/avr-libc , the
avr-libc package provides a subset of the standard C library for Atmel
AVR 8-bit RISC microcontrollers. In addition, the library provides the
basic startup code needed by most applications.

Support for this library in crosstool-ng is only enabled for the AVR
8-bit target.

The avr-libc manual and most distributions build the AVR 8-bit gcc
toolchain with the "avr" (non-canonical) target.
Some experimentation also led to the conclusion that other (canonical)
targets are not very well supported, so we force the "avr" target for
crosstool-ng as well.

The manual also recommends building avr-libc after the final gcc build.
To accomplish this with crosstool-ng, a new do_libc_post_cc step is
added, in which currently only avr-libc performs its build, and is a
no-op for the other libc options.

ffe80db73c libc: get rid of libc_finish
At long last, we no longer have any libc that requries a libc_finish.
Yeah!

15a1cc2491 libc: remove now unneeded do_libc_headers
do_libc_headers is now a noop, and is no longer used, so remove that step.

b8b7843bea Get rid of all stuff related to building a /delivery' traball:
- building a delivery tarball has long been broken (since crostool-Ng is installable)
- get rid of implied do_print_filename, that can be mis-leading now tarballs can not be built

Yann E. MORIN"
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.
