/* This is a hack for the gas/all/redef2.s test. This test causes symbols
to be cloned, and without this test relocs would still be generated
against the original pre-cloned symbol. Such symbols would not appear
against the original, pre-cloned symbol. Such symbols would not appear
in the symbol table however, and so a valid reloc could not be
generated. So check to see if the fixup is against a symbol which has
been removed from the symbol chain, and if it is, then allow it to be
adjusted into a reloc against a section symbol. */
