	* elf32-mips.c (mips_reloc_map): Add BFD_RELOC_MIPS_JALR.
	* elfxx-mips.c (JAL_TO_BAL_P): New define to transform JAL to BAL
	for CPUs.  It is true for RM9000.
	(JALR_TO_BAL_P): New define to transform JALR to BAL.  It is true
	for all CPUs.
	(mips_elf_perform_relocation): Use JAL_TO_BAL_P and JALR_TO_BAL_P
	to guard the transformation.
