Hi Bernd,

Thanks for the patch.

When trying to compile this new version on a aarch64 config,
the compilation fails with:

/buildroot/output/build/bpftrace-0.25.1/src/bpffeature.cpp:463:41: 
error: ‘BPF_TRACE_KPROBE_SESSION’ was not declared in this scope

So either it should use the definition from the kernel header,
introduced in v6.10:
https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/commit/?id=535a3692ba7245792e6f23654507865d4293c850

or it should use the definition included from libbpf, and there is
a problem with it. Maybe our libbpf is too old.

Could you have a look please?
