Subject: [PATCH] Set proper directory for baked in macOS LLVM_DIR
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Some users (including myself) were seeing llvm@4 unpacked to 4.0.1_1 instead of 4.0.1. Stuff unpacked to the Cellar directory appears to be a kind of implementation detail — /usr/local/opt is the proper place to reference here.
