It looks like we've still got the same FPU emulator from the Walnut
(405GP) days. Way back when (2001?), softfloat was orders of magnitude
faster on a Walnut. There's the timings for an awk command issued
during a kernel build at the time:
emulate: 113.554u 2778.750s 52:30.75 91.7%
softfloat: 7.607u 1.447s 0:10.57 85.5%
This was the only reason we did softfloat at the time.
