Now with my workaround applied and the original randconfig that triggered
the failure, I get another problem:

drivers/base/power/wakeup.c:68:1: error: data definition has no type
or storage class [-Werror]
 DEFINE_STATIC_SRCU(wakeup_srcu);

Evidently there is at least one driver that uses SRCU but doesn't 'select SRCU'
in Kconfig. There are probably others that just haven't been found.
