gold: powerpc: Test whether sym is not a plugin in do_gc_mark_symbol
sym->object() could be either a Plugin or Powerpc_relobj. There could
be a situation when Pluginobj would be proccessed in
ppc_object->get_opd_ent(dst_off) as Powerpc_relobj and it leads to the
segmentation fault.
* powerpc.cc (do_gc_mark_symbol): Don't segfault on plugin symbols.
