libpng has an entry in upstream_tracking.inc with a 
RECIPE_NO_UPDATE_REASON of "1.4.3 and later changes the API and breaks 
libmatchbox. Sticking with the 1.2.x series instead"

So if libmatchbox now builds with 1.5, we can remove the 1.2.x recipe 
for good. Otherwise we may need both versions, and need to ensure 
libmatchbox will use 1.2.x if it still requires it.
