This case continuously fails on Arm64, so let's not forget to land the
fix.

I agreed with Namhyung for consolidation the test as possible.

@Thomas, could you test on s390 for below change?  And if you could
confirm the 'fp' mode for callgraph is supported on s390, then we even
can unify the event attribute:

  eventattr='max-stack=4'

Thanks,
Leo
