Add support for DT_MIPS_RLD_MAP_REL.

This tag allows debugging of MIPS position independent executables
and provides access to shared library information.

	* elf/elf.h (DT_MIPS_RLD_MAP_REL): New macro.
	(DT_MIPS_NUM): Update.
	* sysdeps/mips/dl-machine.h (ELF_MACHINE_DEBUG_SETUP): Handle
	DT_MIPS_RLD_MAP_REL.
