is always added regardless of the BUILDLINK_DEPTH. This is because these
buildlink3.mk files may be included by bsd.prefs.mk, which is often
included other buildlink3.mk files, and we need to ensure that regardless
of the depth, we are using the correct compiler.

PKGNAME if we are installing to an alternative location so that the
pkg system doesn't complain about conflicts.
Now it is possible to install a gcc3 tree to some location where
it can be used to bootstrap another instance of itself...
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)
