We happen to know that for the PPC target the FP status flags (and in

floating point operation, and so can_use_fpu() will always return
false. So we speed things up a little by forcing QEMU_NO_HARDFLOAT
to true on that target.
We would like to build softfloat once for all targets; that means
removing target-specific ifdefs. Remove the check for TARGET_PPC;
this won't change behaviour because can_use_fpu() will see that
float_flag_inexact is clear and take the softfloat path anyway.

This makes ppc no different from the many other targets which clear out softfloat
exception flags after every operation.
