mk-kinds-h.sh: Define GFC_REAL_*_LITERAL_SUFFIX and GFC_REAL_*_LITERAL macros for each kind.

	* mk-kinds-h.sh: Define GFC_REAL_*_LITERAL_SUFFIX and
	GFC_REAL_*_LITERAL macros for each kind.
	* intrinsics/cpu_time.c (cpu_time_4, cpu_time_8, cpu_time_10,
	cpu_time_16): Use them.
	* intrinsics/random.c (rnumber_4, rnumber_8, rnumber_10,
	rnumber_16): Likewise.
