	* config/mips/sde.h (DRIVER_SELF_SPECS): Add commas.
	Treat -mno-data-in-code and -mcode-xonly as aliases for
	-mcode-readable=no and -mcode-readable=pcrel respectively.
	* config/mips/t-sde (TARGET_LIBGCC2_CFLAGS): Add -mcode-xonly.
	(MULTILIB_OPTIONS): Add -mcode-readable=no multilibs.
	(MULTILIB_DIRNAMES): Update accordingly.
