fpu: Don't compile-time disable hardfloat for PPC targets

We happen to know that for the PPC target the FP status flags (and in
particular float_flag_inexact) will always be cleared before a
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.
