[PATCH] D40217: [LIT] Fix testing out-of-tree Clang builds

[Michał Górny via Phabricator via cfe-commits]

mgorny added a comment.

Or even more abstract (if we assume we don't have to check for presence of `llvm_tools_dir`):

  path_vars = ['clang_tools_dir', 'llvm_tools_dir']
  paths = [getattr(self.config, k) for k in path_vars if hasattr(self.config, k)]

(untested)
