aurel32 e755699dc7 Always enable precise emulation when softfloat is used 
The patch below changes the way to enable softfloat on the PPC target. It
is now enabled when softfloat is used. The rationale behind this change
is that persons who want precise emulation prefer precision over emulation
speed.
