    python-native: don't cause a full regeneration of the built sources
    
    When cross-compiling Python 2 you need a native pgen binary, but the cross
    recipe can't do this on it's own so we build it in python-native and install it.
    
    The rule to build pgen was also causing a complete rebuild of all of the
    generated sources, which meant that building Python 2 needs a *host* Python 2.
    
    This can be fixed by simply building pgen, as this is all we need to install.
