I'm not sure if it's related but I think we are mixing host and
target grub2. When you run ~output/host/usr/sbin/grub-install
any scripts it runs such as grub-mkimage are run from the
build hosts /usr/... and not buildroot HOSTDIR or TARGETDIR
I have been getting elf header mismatches which I think are
differences between grub 2.00 and grub 2.01-beta
