50701cc170 gold: enable new dtags by default
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.
