-mno-fancy-math-387 disables generation of fsqrt, fsin, and several other
instructions. It was needed long ago when FreeBSD supported FPUless 80386 and
80486 systems via a partial in-kernel emulator that couldn't cope with these
instructions. Support for FPUless x86 machines was dropped many years ago, and
the emulator is gone, so -mfancy-math-387 should be the default for FreeBSD.
