>Description:

Since gobject-introspection does reliably not work on some systems,
all pkgs that do .include "../../devel/gobject-introspection/buildlink3.mk"
need to also offer a pkg option "introspection" to disable it.

>How-To-Repeat:
Source code inspection (or try to build some pkgs on an affected system).

>Fix:
n/a
