I'm guessing that should be $OPAL_CUDA_SUPPORT...?

[jsquyres]

Rather than merge this to master, it might simply be a good starting point for @rolfv -- i.e., he can grab this branch from @rhc54, finish the work, and then file a new PR. This would avoid the potential symbol conflicts on master (because Ralph simply copied the affinity extension as a skeleton, etc.).

@rolfv sound good? I can help you out with the git stuff to do this today, if it helps.
