As I said, this didn't work for me, after trying quite a few things (not specifying anything, using with-ils/with-cloog, build cloog/isl in several ways...). I could try to reproduce the issues and open PRs, but it doesn't seem worth the time. My advice would be: use the script or disable graphite, and be happy. In any case, I am not going to commit the patch, I'll keep it local. Anyone feel free to take it and do what you wish with it. I think there are some nice parts even if cloog and isl are removed.
