Hi Arnaud,
Currently Ada bootstrap is broken for bootstrap compiler == gcc-trunk, and
platform == powerpc-darwin9 (although it is possible to bootstrap with gcc-4.9).
The reason is that generations of sinfo.h appears now to _require_ support for
atomics (I assume that's intended).
In fact, w.r.t atomics there's no need to treat powerpc-darwin any differently
from other ppc platform.
The patch below enables them which restores bootstrap and fixes 15 acts and 8
gnat regressions (which essentially, leaves GCC trunk on parity with gcc-4.9
for Ada on the powerpc-darwin9 platform).
This is a bootstrap fail, albeit for an unmentioned target - however, it is
entirely local to the platform, so
OK for trunk?

Tested on powerpc-darwin9, x86_86-darwin12 and x86_64-darwin12 X
powerpc-darwin9 (and by Dominique too, thanks!).
