We are fixing the "generic" soft-float failures (slowly). The count decremented
a few within the last few days. It is mostly about corner cases not very
important in the wild (i.e. we ran many softfloat only architectures for
years w/o even noticing the issues).

In this case I am not sure what to prefer, is there a measurable difference?
I am not sure what serious floating point stuff anyone would run on
such a machine, maybe some Perl benchmarks?

I would like to see both options work (since Nat has them both mostly ready).
