Turn off debug symbols

It looks like hyper may have fixed our memory issue after all. I'd still
like to spend some time looking at heap dumps because I still think our
memory usage is higher than reasonable, but it's low priority and not
something I'm going to do this week, and leaving debug info on makes our
binaries *huge*
