	* config/m68k/lb1sf68.asm (__cmpdf2): Fix typo in immediate mask.
	Create wrapper and rename body...
	(__cmpdf2_internal): ... to this.  Return correct value for unordered
	result.
	(__cmpsf2): Create wrapper and rename body...
	(__cmpsf2_internal): ... to this.  Return corerct value for unordered
	result.
	(__eqdf2, __nedf2, __gtdf2, __gedf2, __ltdf2, __ledf2): Use
	__cmpdf2_internal.
	(__eqsf2, __nesf2, __gtsf2, __gesf2, __ltsf2, __lesf2): Use
	__cmpsf2_internal.
