Ya, sorry I should have clarified: This should fix it for recipes that
only include waf.bbclass (e.g. jack and my local waf recipes that were
also getting the same error). I still think that perhaps waf-
samba.bbclass probably shouldn't be inheriting from waf.bbclass if the
intent is that those projects doesn't actually have ${S}/waf.... but to
be fair I haven't looked closely at the recipes that inherit waf-
samba.bbclass.
