    distutils: Run python from the PATH in the -native case as well
    
    The python distutils generate a python wrapper script for each package,
    containing shebang lines pointing to the python executable.
    In our case, this is a fully-qualified path to python-native in the
    recipe-sysroot-native.
    
    Ubuntu 18.04 restricts the useful length of the shebang line to 125
    characters, and Ubuntu 16.04 restricts it to 77. In both cases, the
    staged python script fails to run due to the length of the path to
    the python-native executable.
    
    Replace the shebang line with nativepython or nativepython3 as appropriate.
    The nativepython symlink is installed by the python-native recipe:
    
        #!/usr/bin/env nativepython
    
    We were already doing this for on-target distutils components.
    This change applies the sed-line to -native distutils components as well.
    In this way, -native clients of these components can invoke the wrapper scripts
    directly, without themselves needing to inherit pythonnative.
    
    This works around a known setuptools issue:
    https://github.com/pypa/setuptools/issues/494
    Even once this issue has been resolved upstream,
    we will still need to replace `python` with `nativepython`
