Hi Tony,

I met the same failure with you. I tried with removing '-O2' and it works
for me. So I send it out.

[PATCH 1/1] grub2.inc: remove '-O2' from CFLAGS

[kai]

From: Kai Kang <kai.kang@windriver.com>

It fails to boot grub after upgrade grub to 2.06. According to
description in

https://bugzilla.yoctoproject.org/show_bug.cgi?id=14367

it is introduced by a commit to fix CVE. So remove option '-O2' from
CFLAGS rather than revert the commit to avoid the failure.

[YOCTO #14367]
