* configure.in: Comment out the --enable-newlib-fp-hw option
        as the mathfp library is inaccurate and should not be used.
        * Makefile.am: Add comment regarding the mathfp directory.
        * configure: Regenerated.
        * Makefile.in: Ditto.
        * libm/mathfp/README: New file that details why the mathfp
        directory is not used.
