... to be clear: the above is my "wish list".

If, at the moment, we can enable OvmfPkg and ArmVirtPkg builds in any
shape or form whatsoever, that's already an improvement! So my comments
are not to be taken as disagreement with the currently proposed patch.
I'm just describing how I believe we should do these builds eventually.

Thanks
Laszlo
