commit: http://git.buildroot.net/buildroot/commit/?id=228bdab4344f751ef44bd18033b950376e42ad16
branch: http://git.buildroot.net/buildroot/commit/?id=refs/heads/master
In iptables versions 1.4.20 and 1.4.21, any call to iptables
would generate a message
cannot open connlabel.conf, not registering 'connlabel' match: No
such file or directory
This problem was reported at [1] and subsequently fixed with commit [2], but
no upstream release has been made since. This patch imports the fix into
Buildroot, awaiting a new release of iptables.

+Subject: extensions: libxt_connlabel: do not open config file from _init hook
+
+else, static builds will print this for every iptables invocation,
+even 'iptables -L'. Delay open until we need to translate a mapping.
