work on mips and powerpc at least.
See http://gcc.gnu.org/bugzilla/show_bug.cgi?id=9091.
The fix therein (which was applied to the 3.3 branch does not really fix
the underlying problem, and is for powerpc only.
While I'm not an ada expert and this pkg wasn't used for more than
bootstrapping itself, I'd consider gnatpsta dispensable.
-USE_NEW_TEXINFO, saves some patches
-symlink libiberty.a into build tree instead of buildlink/lib,
saves some patches
-put common make rules into Makefile.common (for all) and
buildaddon.mk (for all but the base "c" pkg)
