on a related note, is there something I have to do to make the compiler bootstrap on x86_64?

on x86_64 I checked out a fresh branch this morning, and my bootstrap fails trying to configure cilk runtime. It was doing it yesterday to me when I updated, so I tried a fresh checkout this morning.. same thing.

its actually just configured pretty blandly on x86_64-unknown-linux-gnu...
