We can add the compiler test that will throw an error if they aren't
using spinlocks, and they have to use a configure flag to enable it.
The only issue there is that this is going to throw up perhaps many
cases we haven't gotten working, and they might dribble out for weeks or
after final, while a clean solution could break more platforms in the
short term, but could catch more in the long term.
