supported natively, so no external patches needed anymore.
Note that this port requires up-to-date avr-binutils, since a few things
in the assembler syntax have been changed.
Not yet tested on the alpha platform.
Since gcc (in the assumption of generating a native compiler) doesn't
want to cbe configured for an alpha*-*-freebsd* system, we hack the
configure script to allow this (similarly to netbsd). In the end, all
this will be ignored anyway since it's getting to become a
cross-compiler.
