Fix SUPERH builds that select SYS_SUPPORTS_NUMA but do not select SYS_SUPPORTS_SMP and SMP.
kernel/sched/topology.c is only built for CONFIG_SMP and then the NUMA code + data inside topology.c is only built when CONFIG_NUMA is set/enabled, so these arch/sh/ configs need to select SMP and SYS_SUPPORTS_SMP to build the NUMA support.
Fixes this build error in multiple SUPERH configs:
mm/page_alloc.o: In function `get_page_from_freelist': page_alloc.c:(.text+0x2ca8): undefined reference to `node_reclaim_distance'
Fixes: 357d59469c11 ("sh: Tidy up dependencies for SH-2 build.") Fixes: 9109a30e5a54 ("sh: add support for sh7366 processor") Fixes: 55ba99eb211a ("sh: Add support for SH7786 CPU subtype.")
