   All right!  This patch is approved.

Not all right!  Nick, did you actually test this patch?  The subject
of this thread is making sparc64 use -gdwarf2 instead of -gstabs, but
the patch changes it to -gdwarf-2 (note the extra dash).  This isn't
accepted by gas on my OpenBSD/amd64 and OpenBSD/sparc64 systems, and
AFAICT it isn't accepted by the current gas from CVS either.
