Oh right. I didn't know if it was something in cloog or not.

I got past that error after rebuilding and reinstalling but again a
failure in cloog after a ct-ng clean and ct-ng build:

I'm surprised these kinds of things aren't being caught earlier. Is
there no automated regression suite in crosstool-ng that builds all of
these targets on a daily basis? I'd like to help out since last time I
tried ct-ng it failed for other reasons :-)
