MacOS: ots(OpenType Sanitizer), brew install and make fails

I’m trying to install the additional dependency ots.

ots builds fine for me on Ubuntu 18, but I haven’t been able to install on MacOS 10.11 by following the provided instructions.

First I try installing with HomeBrew 1.6.9 + xcode-select version 2343 and GNU Make 3.81, like so…

# install ots
brew tap bramstein/webfonttools;
brew update;
brew install ots --HEAD;

… and get the following error:

Last 15 lines from /Users/eli/Library/Logs/Homebrew/ots/03.make:

At this point, I try installing manually as is described in the ots readme here, but get the same error.

You can also try the OSX binaries I provide on GitHub releases.

if you do, then please open a complementary pull request for that.

Thanks, @eliheuer!
