Hello,
I am trying to build samples/bpf in kernel(5.2.0-rc1) but unsuccessful
with below errors. Can you help to point what i am missing or if there
is some known issue?

I have not seen this issue and it has been some time since I built BPF
samples, sorry. I am mostly building BPF programs through bcc/bpftrace
and Android's build system.
We ought to make samples easier to build though, I remember when I
built it last year there were header related issues which should be
fixed. It could be that new BPF features broke it again.

By the way have you just tried building it on an ARM debian chroot? It
is not worth IMO spending time on cross compiler issues if you can
just native compile it within a chroot (as I do). Cross compilation
does not get a lot of testing, so even if we fix it its likely to come
up again as I've experienced. If you want a debian chroot that is
Android friendly, you can find one here:
https://github.com/joelagnel/adeb (comes with llvm, gcc etc). I have
done lots of native compilation on a Pixel phone.
