* config/cris/linux.h: Sanity-check TARGET_CPU_DEFAULT for
	presence and contents.
	(CRIS_SUBTARGET_DEFAULT_ARCH): New macro, MASK_AVOID_GOTPLT for
	v32, 0 otherwise.
	(CRIS_CPP_SUBTARGET_SPEC, CRIS_CC1_SUBTARGET_SPEC,
	CRIS_ASM_SUBTARGET_SPEC): Adjust for different
	TARGET_CPU_DEFAULT.
	(CRIS_SUBTARGET_DEFAULT): Add CRIS_SUBTARGET_DEFAULT_ARCH.
