i386: Mark NUMA support experimental 



I did some testing and found quite a lot of problems (doesn't
boot at all on non NUMA and misassigns cores on Opteron systems).

Mark it as experimental and warn against its use for now.

It's still default y for SUMMIT/NUMAQ because it'll presumably
work on these systems.

	  NUMA support for i386. This is currently high experimental

	  and should be only used for kernel development. It might also

	  cause boot failures.
