I think you need this patch:

http://git.savannah.gnu.org/cgit/grub.git/commit/?id=67dba97e4598eaf2deb14da044fbfb1c119cf76f

And more background info can be found in the discussion:

https://lists.gnu.org/archive/html/grub-devel/2016-02/msg00011.html

A caveat:

You might face build error on xen platform after, that all_videos module fails
in grub-module-verifier which says no .symtab or .moddep sections found in it.
The check could be overly too active, since it's possible that all_videos
without both sections if the target platform don't have any video module
supported. 

In that we add a band-aided fix by relaxing the check in grub-module-verifier

CCed the patch author, and I think Andrei might be interested to have a look.

Thanks,
