--- Comment #10 from Alan Modra <amodra at gmail dot com> ---
I think coff_link_check_archive_element is just plain broken.  It really has no
business reading symbols from the archive element to check against undefined
symbols in the linker hash table.  That already has been done by
_bfd_generic_link_add_archive_symbols when the armap symbols are checked
against undefined symbols..  For lto objects, checking the symbols again of
course checks the wrong symbols, because the lto symbols are not available
until after the plugin has claimed the archive element!
