Possible bug in softfloat

[Steve Kargl]

In a thread on comp.lang.c, it was pointed out that softfloat
has a bug and in checking src/lib/libc/softfloat I confimed
the issue is present in FreeBSD.  What I hae not confirmed 
is whether or not it is possible to hit this bug.  In fact,
it may only hit arm and mips.  Anyway, here's the patch
