[Impact]
On arm64 platforms, GRUB may occasionally crash after being executed by shim. We're seeing it on the order of 1/100 boots.

[Test Case]
Put an arm64 server in a reboot loop. We're seeing this w/ a Cortex A72-based system (Nvidia Bluefield).

[Fix]
https://github.com/rhboot/shim/pull/504

[What could go wrong]
This currently proposed fix requires GCC, so any use cases (tests, derivative distros) that may require rebuilding shim with other compilers would be impacted. Though that of course falls outside of Ubuntu support.
