If you build a kernel with network and nfs support, but without any
Ethernet (or Ethernet-like devices that support ARP), you'll get several
undefined symbols from module krpc_subr.o when you get to the link stage.
This is because the module krpc_subr.o should not be included in a kernel
that doesn't have ARP-able device support.

I've already sent in a PR (no number yet), but you can apply the following
patch to sys/conf/files to prevent the inclusion of krpc_subr.o in your
kernel.  Remember to re-run config and make depend!
