score.c (score_handle_option): Don't assert that global structures are in use.

	* config/score/score.c (score_handle_option): Don't assert that
	global structures are in use.  Access target_flags via opts
	pointer.  Use value of -march= option to determine target_flags
	settings.
	* config/score/score.opt (march=): Use Enum.
	(score_arch): New Enum and EnumValue entries.
