I don't think the logic changed in "support/kconfig: reference
environment variables directly (remove 'option env=')" can work with
the current kconfig code base.

But we'd hate to stay stuck on an old kconfig code base forever. Gtk is
going to move on, Qt is going to move on, which means at some point in
the future, our "make xconfig" and "make gconfig" would no longer work.
