* configure.host: Add check for --enable-newlib-io-pos-args
        and define WANT_IO_POS_ARGS flag if enabled.  Define
        the flag by default for x86-linux configurations.
        * configure.in: Add support for --enable-newlib-io-pos-args.
        * libc/configure.in: Ditto.
        * configure: Regenerated.
        * libc/configure: Ditto.
        * libc/stdio/Makefile.am: Specify -fshort-enums for compiling
        vfprintf.c and vfiprintf.c.
        * libc/stdio/Makefile.in: Regenerated.
        * libc/stdio/vfprintf.c: Add positional argument support that
        is enabled by compiling with -DWANT_IO_POS_ARGS.
