Perhaps we should just disable all offloading for Darwin, at least unless some
Darwin maintainer steps up and adds the needed support for that.

Well, this won't solve the failures on linux!

Failures on linux ( https://gcc.gnu.org/ml/gcc-regression/2014-11/msg00309.html
) are caused by another issue (not by errors during assembling), I'm
investigating them.
I agree to disable generation of offload IR sections temporary for darwin.

r217773 seems to have fixed this PR for darwin as well as for linux (see
https://gcc.gnu.org/ml/gcc-regression/2014-11/msg00551.html). Closing as FIXED.
