        * configure.host: Add check for --disable-newlib-io-float
        configuration option and add -DNO_FLOATING_POINT to newlib cflags
        if appropriate.
        * acinclude.m4: Added --disable-newlib-io-float option.
        * aclocal.m4: Regenerated.
        * configure: Ditto.
        * doc/aclocal.m4 doc/configure libc/aclocal.m4 libc/configure
        * libc/*/aclocal.m4 libc/*/configure
        * libm/*/aclocal.m4 libm/*/configure: Ditto.
        * libc/stdio/vfprintf.c [!INTEGER_ONLY]: Only set FLOATING_POINT
        if NO_FLOATING_POINT flag is not defined.
