Bug#940628: grub-efi-{non-i386/amd64}-bin: Missing multiboot.mod

[Elliott Mitchell]

Package: src:grub2
Version: 2.02+dfsg1-20
Severity: important

In particular grub-efi-arm-bin should have
/usr/lib/grub/arm-efi/multiboot.mod and grub-efi-arm64-bin should have
/usr/lib/grub/arm64-efi/multiboot.mod

This makes it impossible for GRUB to load Xen on any platform that is not
either i386 or amd64.  Xen has support for running on ARM platforms, but
with no bootloader...

For example there is known to be working UEFI third-stage firmware for
the Raspberry PI:
https://github.com/tianocore/edk2-platforms/tree/master/Platform/RaspberryPi/RPi3

The absence of /usr/lib/grub/arm64-efi/multiboot.mod means entries
generated by /etc/grub.d/20_linux_xen cannot work.
