libbattlecode-linux.a is not compiled with optimization

Hard to make a PR for without more insight into the release processes, but the libbattlecode-linux.a I see in the scafford does not appear to be compiled with optimization, judging by the assembly. This probably slows the Rust code down by quite a large factor (I didn't measure yet).
Hm, in the current build process it's built with --release; you can run make linux-libs copy-linux in the root directory of the repo to watch the build process. (We build in an ubuntu docker image for linux because the release is orchestrated from a mac machine). I just ran a build and as far as I can tell it used the correct artifacts.
It's possible I screwed up during one of the past releases and used the debug build instead of the release build, or I'm missing something, though.
It's possible that we're accidentally doing something in the codebase that inhibits optimization, as well. There's definitely some low-hanging performance fruit in the engine.
Oh, erm, sorry, I was looking at an old scaffold. Never mind this issue! The current one looks fine.
