[PATCH] stdio: fix nano-vfprintf pointer formating with long pointers

[Peter A. Bigot]

On the MSP430 when building with -mlarge sizeof(void*) is larger than
sizeof(int), resulting in an offset error extracting arguments to format
strings that include %p.

stdio/ChangeLog:
2014-11-19  Peter A. Bigot  <pab@pabigot.com>

        * libc/stdio/nano-vfprintf_i.c (_printf_i): Use LONGINT when void* is
        larger than an int.
