* config/h8300/h8300.c (h8300_init_once): Use MASK_H8300S_1

	instead of MASK_H8300S.
	* config/h8300/h8300.h (target_flags, MASK_H8300S, MASK_MAC,
	MASK_INT32, MASK_ADDRESSES, MASK_QUICKCALL, MASK_SLOWBYTE,
	MASK_NORMAL_MODE, MASK_RELAX, MASK_H8300H, MASK_ALIGN_300,

	TARGET_QUICKCALL, TARGET_SLOWBYTE, TARGET_H8300H,
	TARGET_H8300XS, TARGET_NORMAL_MODE, TARGET_ALIGN_300,
	TARGET_SWITCHES): Remove.
	(TARGET_H8300S): Redefine interms of TARGET_H8300S_1 and
	TARGET_H8300SX.
	* config/h8300/h8300.opt: New.
