  Log:
  Add a floating-point emulator so that a single userland or single ABI
  can run on processors that don't have a FPU. This is typically the
  case for Book E processors. While a tuned system will probably want
  to use soft-float (or use a processor that has a FPU if the usage is
  FP intensive enough), allowing hard-float on FPU-less systems gives
  great portability and flexibility.
