PRU Binutils port

	* readelf.c (guess_is_rela): Add EM_TI_PRU.
	(dump_relocations): Invoke elf_pru_reloc_type.
	(get_machine_name): Handle EM_TI_PRU.
	(is_32bit_abs_reloc): Handle R_PRU_BFD_RELOC_32.
	(is_16bit_abs_reloc): Handle R_PRU_BFD_RELOC_16.
	(is_none_reloc): Handle PRU_NONE and PRU_DIFF variants.
