commit 3c81e9f0e7e06d77528643c749868f7524f572b0
Author: Alexandre Rostovtsev <tetromino gentoo org>

    Prevent the link to libgnome-shell-js.so from being removed
    
    Add a dummy call to shell_js_add_extension_importer() to ensure that the
    link to libgnome-shell-js.so is not removed when using -Wl,--as-needed,
    which is the default on many distros.
