* elf-hppa.h (elf_hppa_final_link_relocate): Handle DLTREL14R and

Browse Source 
DLTREL21L relocs.  Pass the output bfd to elf_hppa_relocate_insn.
        Pass the relocate type rather than the insn format to
        elf_hppa_relocate_insn.
        (elf_hppa_relocate_insn): Make switch dependent on relocation type
        rather than the opcode.  Handle DLTREL21L and DLTREL14R relocs.
