You would have to restrict it to Mach-O.  Other 64-bit targets
continue to use 32-bit stabs, which is arguably incorrect but is a
backward compatibility issue.  So I think the right approach is going
to be to add a new field to the bfd_target structure.  That is a
little painful since you will have to modify all the existing
declarations, but the runtime cost will be low.

My understanding is that Mach-O has switchd to DWARF anyhow.
