Actually that's the reason why i386 doesn't use softfloat, as all the trigonometric use libm, and the bridge between softfloat and libm is not working correctly (plenty of type abuse).
Besides, I doubt softfloat would want bug-compatible trig function implementations. fsincos for example is a far cry from the precision of the libm function.
