        Add stub support for generating Gtk build system from gyp
        https://bugs.webkit.org/show_bug.cgi?id=58086

        This adds support for a new --port argument and plumbs through
        the necessary paths to allow generating for a port other than Mac.

        This does not produce a buildable JavaScriptCore, but it
        does allow running gyp/configure --port=gtk and having
        it generate a gtk.Makefile which we can use for testing
        the rest of the plumbing.

        * gyp/gtk.gyp: Added.
