Thanks.  I'd prefer to have the upstream and pkglibdir parts as separate
patches, though, since that'll make rebasing onto new upstream releases
easier in future.

I cherry-picked the upstream patch (though noting that the version of
that isn't actually the same as the final version you posted to
grub-devel, so you might want to chase that up with Daniel), and applied
a separate patch on top of it to add the pkglibdir bits.

Cheers,
