My way of doing this efficiently is to create throwaway commits, in
git, just to push code around to various physical or virtual machines
in my house. Because git is really fast at pushing incremental changes
around:

But if you eventually find a way to share a filesystem (which wouldn't
slow down the build) between MacOS and a Linux host via qemu or
something like that I'd be interested, that's most ideal of course.
