Currently, samples/bpf, tools/runqslower and bpf/iterators use bpftool
for vmlinux.h, skeleton, and static linking only. We can uselightweight
bootstrap version of bpftool to handle these, and it will be faster.

v2:
- make libbpf and bootstrap bpftool independent. and make it simple.

Quentin, does this patch set look good to you?

[Apologies, the mail server has been filtering Pu's emails as spam for
some reason and I had missed the discussion :s]

Looks OK to me:
Acked-by: Quentin Monnet <quentin@isovalent.com>

Although I'm a bit sorry to see the sharing of libbpf between bpftool
and libbpf go away. But OK. We can maybe reintroduce it through
bpftool's Makefile or a separate include Makefile in the future.

Hi, Quentin,

so much thanks for your review and ack. and apologies for not receiving 
your advice in time due to the misconfiguration of mail server[0]. and 
looking forward to your improvement for bpftool.
