Make fails with error 4, error 5, unreal totally unusable on linux

I have cloned from the git repository, for branch origin/release. I’ve run Setup.sh, GenerateProjectFiles.sh. When I go to run ‘make’ command, it throws 2 errors and stops:

I have no idea how to resolve this or where to start looking.
