Yes, I just noticed this myself.  That line is wrong - directfb is
already being correctly handled by the main recipe, so line 9 should
be removed.  This would then give the correct flags.

I tested this with those lines removed:
   gthomas@europa:/local/p0382-latest_2014-10-07$ bitbake -e cairo | grep ^PACKAGECONFIG
   PACKAGECONFIG="x11             egl glesv2"

This is the correct behaviour - I'll formulate and send a patch.
