fwiw, debian had the same issue around libelf-dev with their kernel
source packaging, and treated it as a bug there, which was resolved in
the kernel package itself, rather than requiring additional build
dependencies of all kernel modules: https://bugs.debian.org/886474

(this message is just about libelf-dev; i haven't followed the details
about objtool)
