Bug#651041: OpenPA atomic primitives

There are three possible solutions for this:
1. You can disable OPA's processor atomics using
--with-atomic-primitives=no as the configure error message states. In
this case, OPA will use locks to emulate atomic operations, which is
slower but works correctly.
2. You can change the device to ch3:sock (using the configure option
--with-device=ch3:sock), which doesn't use shared memory at all and
hence doesn't need OPA atomics.
3. You can contribute m68k processor atomics to OPA, so it is natively
supported and OPA doesn't have to fall back to locks.
