Another fallout of the GOFAST-compatible configuration of GCC is that
we emit calls to __unord[sd]f2 even though such a function is not
present in GOFAST, but we fail to emit it in libgcc. Jim Wilson
agreed this patch was a good fix for this oversight, so I'm checking
it in. Tested on the same port as the previous patch.

* config/fp-bit.c (_unord_f2): Compile it in even if
US_SOFTWARE_GOFAST is enabled.
