[PATCH] powerpc/cell: remove BUILD_BUG_ON and add sys_tee to spu_syscall_table
Every time a new syscall gets added, a BUILD_BUG_ON in arch/powerpc/platforms/cell/spu_callbacks.c gets triggered. Since the addition of a new syscall is rather harmless, the error should just be removed. While we're here, add sys_tee to the list and add a comment to systbl.S to remind people that there is another list on powerpc.
