I have sent a patch for this a couple of days ago to netdev, it hasn't
made it to net-next yet. Here's the latest one:
[PATCH net-next v3] netfilter: xt_hashlimit: Fix link error in 32bit
arch because of 64bit division
This should fix the link error.

I also did a patch (not submitted yet), but my solution used 32-bit
math for the version 1 case. I think that would be better so we
don't slow down 32-bit architectures too much (div_u64_u64
is very slow).
