        and MIPS_R_SWITCH, as well as several empty entries.  Update comment
        for MIPS_R_PCREL16.

        (mips_adjust_reloc_in): Likewise, adjust maximum accepted relocation
        type number to be MIPS_R_PCREL16.
        (mips_relocate_section): Remove support for link-time relaxation
        of branches used by embedded-PIC.  Remove support for MIPS_R_SWITCH,
        MIPS_R_RELLO, and MIPS_R_RELHI relocations.
        (_bfd_ecoff_bfd_relax_section): Redefine to bfd_generic_relax_section.
        * ecoff.c (ecoff_indirect_link_order): Remove support for link-time
        relaxation of branches used by embedded-PIC.
        * ecofflink.c (bfd_ecoff_debug_accumulate): Likewise.
        * libecoff.h (struct ecoff_section_tdata): Remove embedded-PIC
        related members, update comment.
        * pe-mips.c: Remove disabled (commented-out and #if 0'd)
        code related to embedded-PIC.
        * elfxx-mips.c (_bfd_mips_elf_read_ecoff_info): Remove
        initialization of now-removed 'adjust' member of
        'struct ecoff_debug_info'.
