net_if-tests: port to older Solaris Problem reported by Tom G. Christensen in <http://lists.gnu.org/archive/html/bug-gnulib/2013-01/msg00086.html>. * modules/net_if-tests (NET_IF_LIB): New substitution. (test_net_if_LDADD): New makefile macro, which uses NET_IF_LIB. (HAVE_IF_NAMEINDEX): New C macro. * tests/test-net_if.c: Bypass most of the test if !HAVE_IF_NAMEINDEX.
