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.
