while shallow clones is a comprehensive solution and we should probably slot it for 2.3 release
the above recipe should stop using git fetcher and convert to using tarballs
since this git repo hosts binaries, it will bloat with every time they push
stuff into it. Someone should teach these RPi folks to not abuse github.
