[OE-core] [PATCH 1/3] grub-1.99: use gcc-cross for building the target binaries

[nitin.a.kamble at intel.com]

From: Nitin A Kamble <nitin.a.kamble at intel.com>

It was using distro gcc to build binaries for target. This got detected
on fedora 17 alpha, on which it hit an gcc-4.7 issue.

This Fixes Bug: [Yocto #2291]
