    [MIPS] Provide empty irq_enable_hazard definition for legacy and R1 cores.
    Following a strict interpretation the empty definition of irq_enable_hazard
    has always been a bug - but an intentional one because it didn't bite.
    This has now changed, for uniprocessor kernels mm/slab.c:do_drain()
            on_each_cpu(do_drain, cachep, 1, 1);
    may be compiled into a mtc0 c0_status; mfc0 c0_status sequence resulting
    in a back-to-back hazard.
