asm/system.h is one of the messier kernel headers, so i'm not surprised it has
assymetric requirements on 64-bit and 32-bit systems.
We could fix it (provide those dependencies), or we could pick
tools/perf/perf.h's mb() definitions. That's much cruder than the nice kernel
memory barriers though ...
Thanks,
Ingo
