>Description:
	Building a kernel without an ARP-capable device causes undefined
	symbols at kernel link time.  These symbols come from krpc_subr.o
	which should not be included in the kernel if there are no ARP-
	capable devices configured.
>How-To-Repeat:
	Build a minimal kernel with network and nfs client & server support
	but without any network devices except for ppp and/or slip.
>Fix:
	Apply the following patch to sys/files to prevent inclusion of 
	nfs/krpc_subr.o in such kernels:
