407 Use mips_finish_exec_plt to create non-VxWorks PLT headers. Set
409 (_bfd_mips_elf_copy_indirect_symbol): Copy has_static_relocs
410 from the indirect symbol to the direct symbol. Also copy
411 has_nonpic_branches for indirect symbols.
412 (_bfd_mips_elf_get_target_dtag): Handle DT_MIPS_PLTGOT and
