Syslinux - Jun 2010 - [PATCH] mtools/syslinux.c: Silence warnings

From: Gene Cumm <gene.cumm at gmail.com>

mtools/syslinux.c: Silence warnings from GCC with asprintf's attribute
warn_unused_result in certain glibc versions/patches.  Assign it to a
variable and ignore it as the string is already tested for null before
using it.
