Hmmh, actually the Config.in won't allow you to to set
CONFIG_IP_NF_COMPAT_IPCHAINS if CONFIG_IP_NF_CONNTRACK=y, but I don't
really understand that Config.in completely. (CONFIG_IP_NF_NAT_NEEDED is
set, but AFAICS never referenced anywhere).

Anyway, the appended patch fixed the problem for me, vmlinux links okay
now - didn't try if it works, though.
