[PATCH] D56976: [clang] [test] Pass -ccc-install-dir in mac compilation db test

[Ilya Biryukov via Phabricator via cfe-commits]

ilya-biryukov added a comment.

LGTM to unbreak the tests on *BSD, but could you please leave a comment?
It would probably be best to take `argv[0]` into account on *BSD systems as well (possibly only if `clang` could not be found).

At least if that's the behaviour on **all** other systems.


Repository:
  rC Clang
