    When tripping over a GIT_ var, give a useful error
    
    Before the script was failing with "package build failed.  no more
    info". That was very unhelpful. Hopefully this message will make it more
    clear what is wrong and in worst case it will be easier to find which
    call to Exit_error exactly interrupted the execution.
