In what way is with_gtk1=("--enable-gtk" "--disable-gtk") not simple? I
really think that <feature> should be *disabled* (not auto-configured) if
that use_flag is specified as "without" (- instead of +) if it's possible.

If I write "-gtk1" in my system wide useflag conf file, I expect all apps
that *could* be built without gtk 1.x to not build with gtk 1.x. Without
having to set up a chrooted build environment without gtk 1.x...
