So is this a bug in feature misdetection?
In your commit message you state:
"And making all this dependent on HAVE_LIBBFD_SUPPORT and
HAVE_LIBBPF_SUPPORT:"
Now we obviously have libbfd.
But if the HAVE_LIBBPF_SUPPORT means tools/lib/bpf, then I havent
packaged that yet, so why is it detecting it as available ?
