Hi Guix!

I noticed linux 6.4 didn't build on aarch64
https://ci.guix.gnu.org/build/1787394/details, building it locally and
checking the log, it seems we're simply missing the `hexdump' column:

--8<---------------cut here---------------start------------->8---

--8<---------------cut here---------------end--------------->8---

The "PAD" line seems to come from this Makefile, imported in a few
targets: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/drivers/firmware/efi/libstub/Makefile.zboot#n7

So the fix is easy! Somebody probably already found the issue, but I
figure I'd post the fix in case it saves time :-)

Thanks!
Pierre
