I'd recommend -fswitch.    This gives most of the benefit of -f68881 if
you have a 68881, yet will still run perfectly well on a machine
without one.  Recommended for building binaries that want to use 68881s
when available but may need to run without them.

Of course, you should first convince yourself there's enough
floating-point code that the difference is significant....

I entirely agree.
