I tried merging this:

https://github.com/tianocore/edk2/pull/1235

but the Ubuntu builds all failed. I've checked two logs:

https://dev.azure.com/tianocore/edk2-ci/_build/results?buildId=16967&view=logs&j=cf2d8b26-a21c-5c68-abf4-b944c123e462&t=5ffbbe5c-1d3a-55f5-5ef3-8a0ef80d76a1&l=184
https://dev.azure.com/tianocore/edk2-ci/_build/results?buildId=16968&view=logs&j=47cf355a-6eb4-51a8-46a8-ff4028bfcac0&t=beedef5d-00d0-5a8c-fa35-57d7319988c2&l=182

They say,

INFO - /bin/sh: 1: qemu-system-aarch64: not found
INFO - /bin/sh: 1: qemu-system-x86_64: not found

I guess I won't be merging the three patch sets that I had planned for
this evening...
