Failing to build on Mac

[gussmith23]

Some of the issues I'm running into:

1. The clang version on Mac is too old, and can't compile some of the code that build.rs attempts to compile. Fixed by setting CXX= and CC= to newer clang binaries.
2. The system libs hard-coded in build.rs are not the right ones for Mac -- presumably they're for Linux? I just hard-coded the Mac ones, but a better solution would probably be to call llvm-config in build.rs?
3. Finally, I'm not at all sure what's happening here:

Any thoughts? Totally perplexed by the reference to Itanium.

alright, i was able to (hackily) get it working with these changes:

That's fantastic thanks. I haven't tried the build on OSX in a while. Probably worth adding a CI job for it. Out of curiosity: the manual homebrew cellar path you had to add -- would that show up in llvm-config --system-libs --link-static? That might be a portable way of getting at the necessary system libs.

[gussmith23]

Yup, llvm-config provides that info on Mac. Here are various calls to llvm-config and their results on Mac:

Awesome thanks! I've pushed a few changes to master that try to make use of llvm-config for the build. Do these work for you?
