* elf32-hppa.h (hppa_look_for_stub_in_section): Fix typo. Delete
unused symbols argument.
* 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.
