Build fix for OpenBSD - See ticket #2397

Build still failing, but for a different cause:

cpu_set_t

Thanks. I've omitted the CPU pinning code from OpenBSD builds for the time being. I'll look into what the equivalent of cpu_set_t is sometime and try to implement pinning again.

Let me know if this fixes things for you.

[joseph-henry]

Sorry, I just don't have an OpenBSD system up right now to test compiles on. But I think this should fix it.

[juanpeha]

Bingo! Compiles now. Thank you very much.

[joseph-henry]

No problem. Thanks for validating this for us! Have a great day.
