I would expect the libnet* stuff libraries to be run at run-time, so wouldn't they need to be compiled for the --target architecture instead of --system, and hence, 'inputs'? As a test, if you have a non-aarch64 system, you can run $ ./pre-inst-env guix build conntrack-tools --target=aarch64-linux-gnu and see if it actually compiles. Greetings, Maxime.
