The reason for me to stay on v4.20 is that with v5.0-rc8 I don't have ebpf
'raw tracepoint' support any more on my arm64 board. But this issue is not
related to your patch though.

And this is caused by a38d1107f937 (bpf: support raw tracepoints in modules)
which renamed bpf_find_raw_tracepoint() which bcc-tools relies on to detect if
raw tracepoints are supported..

Speaking of fragile depedencies :-)

I guess the check can be extended to check for both symbols - but it'll stay
fragile. Not sure if they can do better.

I filed a bug

https://github.com/iovisor/bcc/issues/2240

This did the trick for me on v5.0-rc8. Thanks, Qais!
