Should we allow 32 bit support into openruko?

I know it doesn't seem like a big deal, but this hack and also another in integration-tests ([see these lines](https://github.com/slotbox/integration-tests/blob/master/tests/60-deploy.sh#L6)) is required to get Openruko running on Travis CI. They're not particularly elegant hacks, but we'll be able to remove them when Travis goes 64 bit, which is soon hopefully.
