[oe] gtk+-directfb

[Steve Sakoman]

I have an interest in building gtk+-directfb for the gumstix platform.

So, of course, I gave it a quick try and it failed because of a
dependency on pango-directfb -- which doesn't exist.

In checking some of the prior traffic on the list, I see that
pango-directfb has been removed due to its causing build breakage.

Has anyone come us with an acceptable approach to supporting a
gtk+-directfb build since then?
