        * elf32-hppa.c (hppa_elf_stub_reloc): Accept asymbol ** rather
        than asymbol * for original target symbol.  All callers changed.
        Set reloc->sym_ptr_ptr appropriately.
        (hppa_elf_build_linker_stub): Set reloc->sym_ptr_ptr correctly.
        (hppa_elf_look_for_stubs_in_section): No longer need symbols
        argument.  Use the output symbols when canonicalizing the relocs,
        creating them if necessary.

        * linker.c (_bfd_generic_link_output_symbols): Do not rebuild/clobber
        the output symbols if they already exist.
