I would say a combination of (1) and (3).

We want to:

 * Enable the gtk3 theme support only when the necessary dependencies
   are met. In this case, it would be BR2_PACKAGE_LIBGTK3_X11, which
   indicates that gtk3 is enabled with its X11 backend.

 * Be explicit about enabling and disabling the gtk3 theme. I.e
   explicitly enable it when BR2_PACKAGE_LIBGTK3_X11=y, explicitly
   disable it otherwise.

Thanks!
