    PR26150, Assertion when asm() defines global symbols, -flto and
--start-group

    If an archive map contains symbols that aren't actually defined by the
    indexed element for any reason, then loading that element will leave
    the symbol undefined (or common).  This leads to the possibility of
    the element being loaded again should the archive be searched again
    due to the action of --start-group/--end-group.  The testcase
    triggering this problem was an archive containing fat lto objects,
    with the archive map incorrectly created by ar rather than gcc-ar.

            * ldlang.c (ldlang_add_file): Assert that we aren't adding the
            current end of link.next list again too.
            * ldmain.c (add_archive_element): Don't load archive elements
            again that have already been loaded.
