[llvm-dev] [EXT] Fix builds on MacOS Mojave [patch]

[Mark Murray via llvm-dev]

Hi

I have macports, but I'm not directly using it - it's just being found by the build process somehow.

The failure shows that /opt/... is being used, but that usage seems broken or incomplete.

    On an OS X install with Xcode, /opt/ is not expected to contain anything in particular; it doesn't make sense to hard-code it into the LLVM build system.

    Are you trying to use homebrew to build LLVM?
