Create release binaries for Mac

[ExcaliburZero]

Currently I generate release binaries for Linux and Windows since I develop on a Linux machine and cross-compiling Rust code for Windows is easy.

We should generate binaries for Mac as well, so that the vscode extension can leverage the language server on Mac.

I want to build binaries for Linux, Mac and Windows. How do I cross compile from Linux to Mac?

Short answer: You don't.

It's hard to find a cross C toolchain (and cross compiled C libraries) between different OSes (except perhaps from Linux to Windows). A much simpler and less error prone way is to build natively for these targets because they are tier 1 platforms. You may not have direct access to all these OSes but that's not a problem because you can use CI services like Travis CI and AppVeyor. Check my rust-everywhere project for instructions on how to do that.
