Subject: Check for dn_skipname() when checking res_search() to resolve µClibc
 compile failures. This works by disabling the DNS alias detection feature,
 which is however deprecated anyways.

+# FIXES:
+* The configure script will additionally check for 'dn_skipname', to fix build
+  failures with µClibc. The new check still recognizes the resolver libraries on
+  Ubuntu 7.04, openSUSE 10.2, Solaris 8, NetBSD 3.0 and FreeBSD 6.2.
+  Fixes Gentoo bug #134187.
+  NOTE: this is a bit of a hack, since we twist the HAVE_RES_SEARCH result, but
+  res_search() and dn_skipname() are only used together and scheduled for
+  removal in future versions, so this is probably fine.
