[patch 1/1] syslinux: add suport for com32 entries in the menu

[Cisneros, Jorge (George)]

From: Jorge D Cisneros <jorge.cisneros@xxxxxx>

Problem: The actual code only check for entries with kernel or linux, so this example will not work, this patch is to add support to gfxboot to detect the entry COM32 and use  any module, in this case the module is chain.c32
Version: Syslinux 4.04


Example:
UI gfxboot.c32

LABEL boot_hd0
MENU LABEL Boot from first hard drive
COM32 chain.c32
APPEND hd0
