When you configure an autoconf package and it probes the installed
RTEMS, there are two files used which should never be used in a
"real application" -- the default crt0.o and the dummy configuration.

The file cpukit/libmisc/dummy.c is where this should go.  I think
cutting and pasting the network configuration from samples/loopback
should be WAY more than it takes.

I think adding something like this will work if
RTEMS_HAS_NETWORKING is the right constant:

#if defined(RTEMS_HAS_NETWORKING)

#include <rtems/rtems_bsdnet.h>

extern void rtems_bsdnet_loopattach();
static struct rtems_bsdnet_ifconfig loopback_config = {
     "lo0",                          /* name */
     (int (*)(struct rtems_bsdnet_ifconfig *, 
int))rtems_bsdnet_loopattach, /* attach function */
     NULL,                           /* link to next interface */
     "127.0.0.1",                    /* IP address */
     "255.0.0.0",                    /* IP net mask */
};

struct rtems_bsdnet_config rtems_bsdnet_config = {
     &loopback_config,       /* Network interface */
     NULL,                   /* Use fixed network configuration */
     0,                      /* Default network task priority */
     0,                      /* Default mbuf capacity */
     0,                      /* Default mbuf cluster capacity */
     "testSystem",           /* Host name */
     "nowhere.com",          /* Domain name */
     "127.0.0.1",            /* Gateway */
     "127.0.0.1",            /* Log host */
     {"127.0.0.1" },         /* Name server(s) */
     {"127.0.0.1" },         /* NTP server(s) */
};
