`perf record` is missing support for `--off-cpu` command line option because it is not compiled in. Could you please enable it?

Additional info:
* package version(s): 6.1-1
* link to upstream bug report, if any: https://lkml.kernel.org/lkml/Ya4CxsyoyFQVFzoi%40kernel.org/T/
Reportedly the feature requires "new enough" Clang, but that should not be an issue in Arch, I believe.

Steps to reproduce:
1. Run `perf record --off-cpu date`
2. Output:
Warning: option `off-cpu' is being ignored because no BUILD_BPF_SKEL=1

Thank you!
This task depends upon

I'm not able to build perf with this option enabled with 6.3.
There are upstream thread about similar issues on another architectures.
