Subject: [PATCH v2 2/4] x86, build: Add new paths for isolinux.bin and ldlinux.c32
Date:   Mon,  6 Nov 2017 11:32:57 +0800

From: Changbin Du <changbin.du@intel.com>

Recently I failed to build isoimage target, because the path of isolinux.bin
changed to /usr/xxx/ISOLINUX/isolinux.bin, as well as ldlinux.c32 which
changed to /usr/xxx/syslinux/modules/bios/ldlinux.c32.

This patch improves the file search logic:
  - Show a error message instead of silent fail.
  - Add above new paths.
