PR22751, LTO broken for libgcc libcalls
So what was happening was that the file added from libgcc.a during the rescan was not put on file_chain. map_input_to_output_sections then doesn't see the file and its sections are treated as discarded. The file_chain list pointer bug was caused by that fact that an archive element claimed by the plugin does not have my_archive set. Or more correctly, the actual archive element does have my_archive set, but this bfd is replaced with a dummy bfd that doesn't have my_archive set. PR 22751 * ldlang.c (find_rescan_insertion): Look past bfds with claim_archive set.
