kernel FPU emulation is incomplete, and doesn't do fsqrt.  it wouldn't
be a big deal if gcc wasn't generating fsqrt, but somehow the default
no-fancy-math flag got lost somewhere in the shuffle from egcs to gcc3.

I think you could work around it by adding "-mno-fancy-math-387" to
CFLAGS/COPTS (I always forget which) and rebuilding the world, to avoid
generating any sqrt calls, or maybe even "-msoft-float" to avoid
generating floating point at all.

apparently appending to an existing PR doesn't re-open it.  this is the
same issue.
