Trying to compile

In case you're looking to compile this, I've struggled with it quite a bit. This PR will point to the upstream repos [what seems to be] properly, but I haven't been able to find a Rust commit that builds everything. 0.9 gets pretty close, but I was stuck on some link_args change which I couldn't find a commit for.

Process:
- change rust submodules, commit
- configure, which builds rust & deps
- make

A smarter move, if I only had access to the cached packages on Arch (might need to talk to strcat), would be to install a prebuilt package, try to build, repeat. This would be so much faster than building Rust over and over, but, even though I'm running Arch, I clear my package cache too often.

(since this PR changes submodule addresses, you'll likely need to re-clone or delete your .git cache)
