Hi Stephen,
The build failure is intentional as not having BPF skeleton support in
the perf tool will remove features. I've just sent:
https://lore.kernel.org/lkml/20230322183108.1380882-1-irogers@google.com/
Which will recommend adding NO_BPF_SKEL=1 to your build options when
this failure occurs. I didn't think a features test was appropriate
for this as the feature test would basically replicate the vmlinux.h
generation and I didn't want to move that support through the build
system.
Thanks,
Ian
