Starting with glibc 2.10, there is no fallback to nameserver 0.0.0.0 anymore if
/etc/resolv.conf is missing. This is due to this change:

2008-12-02  Ulrich Drepper  <drepper@redhat.com>

        * resolv/res_init.c (__res_vinit): Initialize nscount to zero.

This value should be set back to 1 so that the following code is actually useful:
#ifdef USELOOPBACK
        statp->nsaddr.sin_addr = inet_makeaddr(IN_LOOPBACKNET, 1);
#else
        statp->nsaddr.sin_addr.s_addr = INADDR_ANY;
#endif
        statp->nsaddr.sin_family = AF_INET;
        statp->nsaddr.sin_port = htons(NAMESERVER_PORT);

--

                    missing
