runc comments: opencontainers/runc#2566

runc has C code embedded inside it in order to run (this code is a core part of container setup and can't be disabled) -- so you'll need to have libc enabled when you build runc. However you can always just use our static binaries (see the releases page) which mean you don't need libc dependencies at runtime.
