From: Jackie Huang <jackie.huang@windriver.com>

CQID: WIND00441128

grub-efi-native builds grub with efi platform, then run
"grub-mkimage" command with built in cfg and modules to
generate an EFI binary for the target, and deploys it.

It works fine when build on 64bit host, but when we build
x86-64 target on 32bit host, it fails to build 64bit grub,
even if it builds, the 64bit binary "grub-mkimage" would
fail to run to generate EFI.

So the solution is:
Add a target package grub-efi and grub-efi-native depends
on it, grub-efi-native will be back to real native, then
run "grub-mkimage" command with modules in sysroot populated
by grub-efi to generate the EFI binary for target.

Another problem is -mcmodel=large is not supported by gcc
with version lower than 4.4, but we don't need to use
memory over 4GiB, so add a patch to allow compilation
without large model support.

+SUMMARY = "GRUB2 is the next-generation GRand Unified Bootloader"
+
+DESCRIPTION = "GRUB2 is the next generaion of a GPLed bootloader \
+intended to unify bootloading across x86 operating systems. In \
+addition to loading the Linux kernel, it implements the Multiboot \
+standard, which allows for flexible loading of multiple boot images. \
+This recipe builds an EFI binary for the target. It does not install \
+or package anything, it only deploys a target-arch GRUB EFI image."
