This should fix them.  Care to give them a round of testing?

As for explaining what's going on: I was out of my mind when I forced
the function to be defined for L_tf_to_usi, GCC just doesn't use it.
The other variants are only used for GOFAST compatibility.  We might
as well go ahead and take out L_tf_to_usi entirely from Makefile.in
and config/fp-bit.[ch], but there's no good reason to do so, and some
day GCC might be able to use float_to_unsigned anyway, so we might as
well leave it there.
