* powerpc.cc (Target_powerpc::symval_for_branch): Don't assert
on garbage collected .opd section.
* powerpc.cc (Target_powerpc::do_gc_add_reference): Test dst_shndx
is non-zero.
(Target_powerpc::do_gc_mark_symbols): Likewise for sym->shndx().
(Target_powerpc::do_function_location): Likewise for loc->shndx.
