* newlib.hin: (_WANT_IO_POS_ARGS): New define.
        (_WANT_IO_LONG_LONG): Ditto.
        (_WANT_IO_LONG_DOUBLE): Ditto.
        * configure.in: Add new configuration options
        --enable-newlib-io-long-long and --enable-newlib-io-long-double
        which tie to new defines in newlib.hin.
        * configure: Regenerated.
        * configure.host: Add checks for new configuration options.  Also
        fix up check for --enable-newlib-io-pos-args so configuration
        option will override any default for a given platform.
        Remove defining compiler flags for the _WANT_IO* options.
        * libc/stdio/vfprintf.c: Change to use new newlib.hin defines
        instead of looking for old compiler flags.
        * libc/stdio/vfscanf.c: Ditto.
        * libc/stdio/vfieeefp.h: Ditto.
        * libc/machine/powerpc/vfprintf.c: Ditto.
        * libc/machine/powerpc/vfscanf.c: Ditto.
