[Buildroot] [PATCH] syslinux: fix boot hang when host-gcc is 5.3

Syslinux uses the host version of gcc to build to bootloader. On systems
with gcc 5.3, this results in a bootloader that hangs. This issue has
been addressed in upstream syslinux, but an official release has not
been made yet. This commit adds the upstream patch to fix the issue.
