	* elfxx-mips.c (_bfd_mips_elf_size_dynamic_sections): Add DT_DEBUG
	and DT_MIPS_RLD_MAP tags for position-independent executables.
	Do not add DT_DEBUG to shared libraries for any MIPS target.

	* ld-mips-elf/multi-got-1.d: Remove DT_DEBUG tag.  Do not require
	a specific file offset for .dynamic.  Reduce DT_HASH by 8 to account
	for removed tag.
	* ld-mips-elf/tls-multi-got-1.r: Likewise.  Also reduce DT_REL by 8.
	Reduce PLTGOT and symbol values by 16 to account for the removed tag.
	* ld-mips-elf/textrel-1.d: Remove DT_DEBUG tag.
	* ld-mips-elf/rel32-n32.d: Reduce addresses by 16 to account for
	removed DT_DEBUG tag.
	* ld-mips-elf/rel64.d: Likewise.
	* ld-mips-elf/tls-multi-got-1.got: Likewise.
