[for 0.1 release v2] build/boot/roms: skip building gnat on fam15h

[Leah Rowe]

the fam15h boards do not use libgfxinit, instead deferring
to coreboot's old style of graphics initialisation written in C.

libgfxinit is otherwise the only thing that needs gcc-gnat, so
skip building gcc-gnat on coreboot/fam15h_udimm and rdimm.

neox added crossgcc_ada="n" to board.cfg files before, but
forgot to add the handling of it, so these boards still didn't
build on modern distros, where building the old gnat version
was problematic.

with this patch, those fam15h boards should now build, on modern
distros and modern toolchains. this is done by using
the BUILD_LANGUAGES environmental variable, setting it to c,
which tells coreboot to skip building gcc-gnat

MERGE NOTE: this is v2 of the earlier patch, but it actually in
fact sets crossgcc_ada="n" on all of the amd boards, whereas
the v1 patch did not, in this 0.1 buildfix series.
