You need to initialize the submodules when cloning the git directories. If you need help on this google "git submodule init and update"

from rpi3.

I did git submodule init and update.

from rpi3.

Then it should work.

Sorry, but your issue is clearly environmental here and is not something you should ask us to look into. As long as we're not seeing the AppVeyor build fail in the same way as yours (which it doesn't), I'm afraid that this is something you're just going to have to figure out on your own because there's only so much help we can provide on a project that is devoted only to production of binaries for a specific case (AppVeyor automated builds) and is not meant to be used as a starting point for building edk2-platforms.
