You don't have a bogus /include dir, but I bet you'll find -I/include in PPLINC.
It would be interesting to know why it didn't spot cloog. What's in your
top-level $objdir/config.log?
BTW, looking at the logic by which all this gets set, I think we're going to
have to take care not to break the in-tree build stuff - which is also subject
of an ongoing thread. Let me just referesh my memory of what they're discussing.
