netconsole.c:(.init.text+0x9560): undefined reference to `configfs_register_subsystem'
drivers/built-in.o: In function `dynamic_netconsole_exit':
netconsole.c:(.exit.text+0x809): undefined reference to `configfs_unregister_subsystem'

so fix the NETCONSOLE_DYNAMIC depends clause to prevent this.
Based on email suggestion from Ben Hutchings.  Thanks.
