I'm going to merge this at once, because it's blocking other pull
requests.

I can see that this patch reuses the commit message from my commits
90683caedf1e ("ArmVirtPkg/PlatformCI: stick with "ubuntu-18.04" for
now", 2020-12-18) and c487970ac89d ("OvmfPkg/PlatformCI: stick with
"ubuntu-18.04" for now", 2020-12-18).

When I wrote those patches, I obviously did *not* miss EmulatorPkg.
However, EmulatorPkg does not use QEMU in CI -- that's the reason my
series did not cover EmulatorPkg. I did not foresee any reason for
EmulatorPkg's CI tasks to fail with Ubuntu 20.04LTS.

And now that I'm actually checking such an (unexpected) failure, it's
not QEMU-related. Instead, it's a GCC issue:

https://dev.azure.com/tianocore/edk2-ci/_build/results?buildId=17230&view=logs&j=7cda4867-6a98-5508-f20e-3046bf80e19c&t=9a255493-65b4-5c45-e228-bf6eb3567b30&l=1150

Therefore, when I merge this patch, I will update the commit message to
refer to a GCC linking issue rather than to QEMU.

Thanks
Laszlo
