[Bug 2130032] Re: libbpf-tools is not available on s390x

[Andreas Hasenack]

Debian experimental has 0.35.0+ds-2~exp1 which removes some of the s390x
restrictions, but not the d/rules setting (maybe a mistake and they just
didn't notice).

I pushed these changes to
https://code.launchpad.net/~ahasenack/ubuntu/+source/bpfcc/+git/bpfcc/+ref/enable-s390x-for-
libbpf-tools

If they build fine and autopkgtests pass (and I'll check s390x), I'll
sponsor.
