Add support for DT_MIPS_RLD_MAP_REL.

This tag makes it possible to access the debug map when debugging position
independent executables.

bfd/

	* elfxx-mips.c (_bfd_mips_elf_create_dynamic_sections): Use executable
	instead of !shared to indicate an application vs shared library.
	(_bfd_mips_elf_size_dynamic_sections): Likewise.
	(_bfd_mips_elf_finish_dynamic_sections): Handle DT_MIPS_RLD_MAP_REL.
	(_bfd_mips_elf_get_target_dtag): Likewise.

binutils/

	* readelf.c (get_mips_dynamic_type): Handle DT_MIPS_RLD_MAP_REL.

include/

	* elf/mips.h (DT_MIPS_RLD_MAP_REL): New macro.
