* libgcc2.h (LIBGCC2_HAS_SF_MODE): New macro.
	(LIBGCC2_HAS_DF_MODE, LIBGCC2_HAS_TF_MODE, LIBGCC2_HAS_XF_MODE): Make
	the defaults false if BITS_PER_UNIT != 8.
	(SFtype, SCtype, __fixsfdi, __floatdisf, __fixunssfSI, __fixunssfDI)
	(__powisf2, __divsc3, __mulsc3): Guard with LIBGCC2_HAS_SF_MODE rather
	than BITS_PER_UNIT != 8.
	(L_fixdfdi, L_fixsfdi, L_fixtfdi, L_fixunsdfdi, L_fixunsdfsi)
	(L_fixunssfdi, L_fixunssfsi, L_fixunstfdi, L_fixunsxfdi, L_fixunsxfsi)
	(L_fixxfdi, L_floatdidf, L_floatdisf, L_floatditf, L_floatdixf): Remove
	#undefs.
	* libgcc2.c (__fixunssfDI, __fixsfdi, __floatdisf, __fixunssfSI)
	(__powisf2, __divsc3, __mulsc3): Guard with LIBGCC2_HAS_SF_MODE.
