That suggests this system doesn't have a GPU switching mechanism, so may 
have the Intel GPU permanently disabled (try xrandr --listproviders as a 
further check), making it unable to run beignet.

However, _crashing_ in that situation is still a bug; the outside-chroot 
crash looks like the known upstream issue (24b2ad.patch), but the 
inside-chroot one looks like a new problem (779213.patch).  Do these help?

(Please don't upload yet, I need to test them on hardware where beignet 
does run first, and also plan to include 
http://cgit.freedesktop.org/beignet/commit/?h=Release_v1.0&id=1c24f07213bcf302ffd6cc751f575dba10f1518d
