Remove any reference to libfloat. That has gone once and for all.
Rationale:
Most of the time, soft-float problems are caused by this sucker of gcc:
it has support for soft float for all of the targets I've tried so far,
but does not activate this code until you dwelve into half a dozen of
files to make it accept to build and link the support code...
So, yes: gcc has soft-float support. And again, yes: gcc is a sucker.
