The powerpc64 get_synthetic_symtab will use both dynamic and static
symbol tables.  Handy when debugging stripped objects.  So both symbols
tables need to be read before calling bfd_get_synthetic_symtab.

Which I see you do in this patch too.  I didn't know about your patch
when I wrote mine..  The order of processing doesn't matter at all.
It just fell out that way in my patch.  Incidentally, why did you
need to fudge the synthetic syms?

+	  synth_symbol_table[i]->flags |= BSF_GLOBAL;

Seems like this should be done in bfd if necessary.
