* elfxx-mips.c (LOAD_INTERLOCKS_P): New define.

    * elfxx-mips.c (LOAD_INTERLOCKS_P): New define.
        (_bfd_mips_elf_size_dynamic_sections): For CPUs without load
        interlocking, the last PLT entry needs a nop in the branch delay slot.
        (_bfd_mips_elf_finish_dynamic_symbol): For CPUs with load itnerlocking,
        output the last two PLT entries in reverse order.

        * ld-mips-elf/pic-and-nonpic-3b.dd,
        ld-mips-elf/pic-and-nonpic-5b.dd,
        ld-mips-elf/pic-and-nonpic-6-o32.dd: Updated to use new PLT entries.
