Add static support

[malept]

See:

• Add option to build against the Ruby static library steveklabnik/ruby-sys#16
• Build native extensions as static libraries d-unsed/ruru#50

This would be such a great improvement. Deploying Rust extensions becomes tedious without this. I am working a gem with bindings to woothee-rust and downloading the compiled lib is a great option for deploying to servers without an updated version of Rust/Cargo. It will make installation for users as simple as a bundle install, thus increasing the adoption of Rust 👍

Most of the hard part is dealing with non-Linux platforms, I would greatly appreciate help with Windows/macOS.

@malept Unforuntately I cannot help there (linux user). Even if Mac/Windows wasn't stable at first, I think this would still be a large win. Currently I cannot deploy rust extensions without it 😢

@ianks have you tried using Ruru with the ruby-sys branch linked in the issue summary? I would be happy to get feedback on that.
