+Subject: iptables: link against libnetfilter_conntrack
+
+Linking currently fails in --enable-static case:
+
+../extensions/libext.a(libxt_connlabel.o): In function `connlabel_get_name':
+iptables/extensions/libxt_connlabel.c:57: undefined reference to `nfct_labelmap_get_name'
+[..]
+It's libxtables.la(libxt_connlabel.o) using libnetfilter_conntrack.
+
+If libnetfilter_conntrack is not found, @libnetfilter_conntrack_CFLAGS@
+and @libnetfilter_conntrack_LIBS@ (and their ${} ones) should be empty,
+therefore producing no harm to include unconditionally.
