Compiler support is already done. Done !

Currently it emits all the most common instructions that our FPU
supports. These are fadd, fsub, fmul, fdiv. If you add support for
others in the FPU core, then it is a matter of minutes that I add
support to the GCC. I don't think we need fsqrt and log functions as
much as we need integer<->float conversion.

So integer<->float is currently done in software library (automatically
generated when building GCC for OpenRISC).
