2013-01-18gold: enable new dtags by defaultMike Frysinger2-1/+5
The "new" dtags options have been around for 14+ years, and for all the targets that gold supports, these flags have always existed. So enable them by default. Having behavior be different from ld.bfd isn't new, and this behavior is the "better" one, so there shouldn't be a problem based on that. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
