Developing with native-image/Truffle on OSX

[Timothy Baldridge]

Been planning to do a dive into SubstrateVM and Truffle, having written
several interpreters in PyPy's toolchain. However, I can't seem to find any
tutorials on how to get GrallVM, native-image, and Truffle all working on
OSX. Is it possible today or do I need to dig up a Linux box?

I don't mind building stuff from source, but the "Getting started" docs on
Graal were a bit sparse, saying run `mx vm ` to start Graal, doesn't help
me much.
