 openssl fails on FPU emulation for powerpc
 
 When machdep.fpu_present sysctl variable can be retrieved, and
 its value is zero, avoid using FPU arithmetic.
 
 FPU is absent and emulated by kernel in that case, and calculation
 results are not correct in bit-to-bit precision.
 
 This behavior should be useful even if we could fix FPU emulation;
 it is much faster to skip FPU arithmetic in general, rather than
 relying upon emulation by kernel via illegal instruction handler.
