If the test doesn't use any library function's run-time behavior, you can
usually do something like

main() {
int a[(2.0+2.0==4.0)?1:-1]
}

This will fail to compile if the floating-point arithmetic is broken.

Otherwise a good solution might be to print a warning if configure detects
the flag.  Or we can strip it out unconditionally, but that seems wrong.
The user should be made aware of the problem.
