AFAIU, you _have_ to specify --with-x-toolkit=VALUE at configure time;
there's no default.  If you don't specify it, you get an X build with
no toolkit.

As for PGTK: we didn't yet decide whether to promote it as the
recommended toolkit.  AFAIU, there are some issues with it (whose root
cause is how Wayland works), and we are not yet sure whether users
will live in peace with those issues.  We need more feedback and more
user experience for that.
