There is another issue with this commit. iptables.h included from m_ipt.c
includes  xtables.h which includes <xtables-version.h> which is not
available on a system without xtables.

I don't see any dependencies from kernel side uapi headers to iptables or
xtables in my tree based on v4.5-rc2. Maybe this is a problem in
iproute2.

Right, it's an iproute2 issue in the commit to backport these original
changes to iproute2:

    Update to current iptables headers
    
    Keep in sync with current iptables upstream
