[Bug 1321335] [NEW] Build failure when ZFS support is enabled

[Rjvbertin]

Public bug reported:

I downloaded the GRUB2 sources from Launchpad, version 2.02~beta2-9 for
"Trusty", in order to understand why grub-probe would not deal correctly
with ZFS pools.

It turns out that even the original source, without the Ubuntu patches,
fails to build when libzfs is present (and/or --enable-zfs is used)
because the zfs libraries are missing from the grub-ofpathname utility's
link command.

Consequently, I think that the grub-probe error I reported in the linked
question is due to missing ZFS support in the binary GRUB2 packages
distributed via Launchpad.

After correcting Makefile.util.def, everything builds OK and grub-probe
correctly reports that ZFS pools are of type zfs .

A patchfile for the correction is attached, and an upstream bug report
created (https://savannah.gnu.org/bugs/index.php?42392).

I'm currently building an updated set of Ubuntu/Debian packages; I'll
modify this ticket (or file a new one) if there are additional issues
booting off a ZFS root.
