using perf tools on ARM64

[voitylov]

I'm trying to use "perf" tool on ARM64 node. It seems like PERF_HW_EVENTS (PMU) is disabled in the kernels that are available. Would it be possible to enable PERF_HW_EVENTS in the kernel build and provide "perf" packages in the distribution?

Technically, we checked https://github.com/scaleway/kernel-tools/blob/master/aarch64/4.9.30-std/.config and we could not see this flag.
