[RTEMS] Add multilibs for LEON3FT back-to-back store workaround

Replace MULTILIB_EXCEPTIONS with MULTILIB_REQUIRED for readability.
-mfix-gr712rc and -mfix-ut700 are currently equivalent.

	* config/sparc/t-rtems: Add mfix-gr712rc multilibs. Replace
	MULTILIB_EXCEPTIONS with MULTILIB_REQUIRED. Match -mfix-gr712rc
	with -mfix-ut700.
