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

[Peter Smith via llvm-dev]

Hello Mark,

I think I ran into a similar problem at home with macports installed.
At the time I thought it more a problem with macports than clang. The
ticket https://trac.macports.org/ticket/58350 might cover it although
I don't know much more than that.
