Subject: [PATCH] configure.ac:
 only-check-conntrack-when-libnfnetlink-enabled.patch

Package libnetfilter-conntrack depends on package libnfnetlink. iptables
checks package libnetfilter-conntrack whatever its package config
libnfnetlink is enabled or not. When libnfnetlink is disabled but
package libnetfilter-conntrack exists, it fails randomly with:

In file included from
.../iptables/1.4.21-r0/iptables-1.4.21/extensions/libxt_connlabel.c:8:0:

.../tmp/sysroots/qemumips/usr/include/libnetfilter_conntrack/libnetfilter_conntrack.h:14:42:
fatal error: libnfnetlink/linux_nfnetlink.h: No such file or directory

compilation terminated.
GNUmakefile:96: recipe for target 'libxt_connlabel.oo' failed
Only check libnetfilter-conntrack when libnfnetlink is enabled to fix it.
