Awww hell...

This is due to missing softfloat emulations we have..(which we need to have).
Since the quad emulations are quicker to emulate in userland than trapping
into the kernel this really just needs fixing. (I had enabled 
-msoft-quad-float on libgcc earlier this week because things like awk 
which did double -> int conversions wouldn't work otherwise).

I'll look at the library routines over the weekend to see whats missing.
