* 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.
