My understanding is that you don't need this command at all; the included
vmlinux.h already contains the necessary type definitions for libbpf, for
the kernel source version in question - ie: instead of needing to run
pahole or bpftool to extract these definitions from a specific vmlinux
image, this file is distributed with them already included.
