    [build] use some internal functions as build phase steps
    
    change_to_gitdir will locate the git directory properly
    and change to it instead of a crazy hard-coded cd ../../..
    and so on.
    
    overwrite_launcher_script will generate the OS X version
    of the launcher in the install prefix.
