With avr-libc 2.0.0 released, we no longer need to force gcc 4.9.x for
the avr toolchain. So, remove the gcc version constraint and allow it to
follow the default gcc version. There is also no need to force companion
libraries' versions anymore.
The 'experimental' flag was also removed from the description as it
seems to be following upstream development now.
This sample has been build tested on Arch Linux and Ubuntu 14.04 hosts.

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.
Some patches are required in avr-libc for a toolchain with gcc 5.x to
work. These patches are still not part of any avr-libc release version,
so the config sample currently forces 4.9.x to avoid requiring to clone
avr-libc trunk.
