        do it in mips_elf_check_symbols instead.
        (mips_elf_create_stub_symbol): New function.
        (mips_elf_la25_stub_hash, mips_elf_la25_stub_eq): New functions.
        (_bfd_mips_elf_init_stubs, mips_elf_local_pic_function_p): Likewise.

        (mips_elf_calculate_relocation): Redirect branches and jumps to
        a non-PIC stub if one exists.  Check !h->has_static_relocs instead

        relocations for R_MIPS_32, R_MIPS_REL32 and R_MIPS_64.
        (_bfd_mips_elf_create_dynamic_sections): Unconditionally call
        _bfd_elf_create_dynamic_sections.  Unconditionally set up
        htab->splt and htab->sdynbss.  Set htab->srelplt to ".rel.plt"
        if !htab->is_vxworks.  Add non-VxWorks values of
        htab->plt_header_size and htab->plt_entry_size.

        non-branch static relocations.  Set has_nonpic_branches when an la25
        stub might be required.  Set can_make_dynamic_p to TRUE if R_MIPS_32,
        R_MIPS_REL32 and R_MIPS_64 relocations can be made dynamic,
        rather than duplicating the condition.  Do not make them dynamic
        for read-only sections in non-PIC executable objects.
        Do not protect this code with dynobj == NULL || htab->sgot == NULL;
        handle each group of cases separately.  Add a default case that
        sets has_static_relocs for non-GOT relocations that cannot be
        made dynamic.  Don't set is_relocation_target and is_branch_target.
        Reject non-PIC static relocations in shared objects.
        (_bfd_mips_vxworks_adjust_dynamic_symbol): Fold into...
        (_bfd_mips_elf_adjust_dynamic_symbol): ...here, using

        .plt and .got.plt when allocating the first entry.  Generalize
        code to handle REL as well as RELA sections and 64-bit as well as
        32-bit GOT entries.  Complain if we find a static-only reloc
        against an externally-defined symbol and if we cannot create
        dynamic relocations for it.  Allocate copy relocs using
        mips_elf_allocate_dynamic_relocations on non-VxWorks targets.
        Set possibly_dynamic_relocs to 0 when using PLTs or copy relocs.
        Skip reserved .got.plt entries.
        (_bfd_mips_elf_always_size_sections): Use mips_elf_check_symbols

        Do the traversal for relocatable objects too.
        (mips_elf_lay_out_got): Use htab->reserved_gotno instead of
        MIPS_RESERVED_GOTNO.
        (_bfd_mips_elf_size_dynamic_sections): Exclude sdynbss if it
        is empty.  Extend the DT_PLTREL, DT_JMPREL and DT_PLTRELSZ handling
        to non-VxWorks targets.  Only add DT_REL{,A}, DT_REL{,A}SZ and
        DT_REL{,A}ENT if .rel.dyn is nonempty.  Create a symbol for the
        PLT.  Allocate a nop at the end of the PLT.  Allocate DT_MIPS_PLTGOT.
        (mips_elf_create_la25_stub_info): New function.
        (_bfd_mips_elf_finish_dynamic_symbol): Write out PLT entries
        and copy relocs where necessary.  Check pointer_equality_needed.
        (mips_finish_exec_plt): New function.
        (_bfd_mips_elf_finish_dynamic_sections): Always set DT_PLTGOT
        to the beginning of htab->sgot.  Use htab->reserved_gotno instead
        of MIPS_RESERVED_GOTNO.  Assert htab->use_plts_and_copy_relocs
        instead of htab->is_vxworks for DT_PLTREL, DT_PLTRELSZ and DT_JMPREL.
        Set DT_PLTREL to DT_REL instead of DT_RELA on non-VxWorks targets.
        Use mips_finish_exec_plt to create non-VxWorks PLT headers.  Set
        DT_MIPS_PLTGOT.
        (_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
        from the indirect symbol to the direct symbol.  Also copy
        has_nonpic_branches for indirect symbols.
        (_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
        DT_MIPS_RWPLT.
        (_bfd_mips_elf_link_hash_table_create): Initialize the new
        mips_elf_link_hash_table fields.
        (_bfd_mips_vxworks_link_hash_table_create): Set
        use_plts_and_copy_relocs to TRUE.  Use TRUE rather than 1
        when setting is_vxworks.
        (_bfd_mips_elf_use_plts_and_copy_relocs): New function.
        (_bfd_mips_elf_final_link): Call mips_elf_create_la25_stub for
        each la25_stub.
        (_bfd_mips_elf_merge_private_bfd_data): Treat dynamic objects
