    * elf-bfd.h (struct elf_backend_data):
        elf_backend_emit_relocs: New field: Function for emitting
        relocs.
        elf_backend_count_relocs: New field: Function for determining
        the number of relocs to be emitted.
        * elfxx-target.h: Provide default (NULL) values for
        elf_backend_emit_relocs and elf_backend_count_relocs.
        * elflink.h (elf_link_size_reloc_section): Make the hash table
        big enough to hold the relocs counted by either reloc_count or
        o->reloc_count.
        (elf_bfd_final_link) emit_relocs: New boolean, set if relocs
        should be emitted, either because of a command line option
        stored in the info structure or because the target provides a
        special reloc emitting function.
        If the target provides a reloc counting function use it,
        unless performing a relocatable link or emitting all relocs.
        Also set the SEC_RELOC flag on any output section which will
        contain relocs.
        (elf_link_input_bfd): emit_relocs: New boolean, set if relocs
        should be emitted, either because of a command line option
        stored in the info structure or because the target provides a
        special reloc emitting function.
        If the target provides a reloc emitting function, use it,
        unless performing a relocatable link or emitting all relocs.
