its detected at configure time if not found then GCC is not built with Graphite
loop optimizations

I think the fact that you have ppl/cloog installed its trying to use it
general distros dont install them by default and hence more often gcc
with OE is build without them.

what we could have done in OE is disable ppl/cloog exlicitly in
configure
