Nick, I reckon your patch is covering a bug elsewhere.  Symbols in discarded
sections are supposed to be treated as undefined.  See cofflink.c:396. 
section_already_linked is supposed to discard duplicate sections.  Apparently
it doesn't.  Ah ha!  I see _bfd_generic_section_already_linked is setting
SEC_GROUP for the plugin comdat entry in the already_linked list, and then
totally ignores any entry with SEC_GROUP set.
