Some distros split glib-mkenums and other GLib build utilities into a
separate package but the glib-2.0 pkgconfig file pointing to it is
typically shipped as part of the -dev package. This can lead to a
situation where configure thinks it knows where glib-mkenums is but make
then fails because it's not really installed on the system. Check the
existence of the actual executable in addition to querying pkgconfig.
