can _src_dir actually be '' or False? If not, remove "or None"

[Paweł Hajdan Jr., 2016/07/18 14:20:27]

It might be empty, and GetBuildOutputDirectory does an "is None" check.

[tandrii(chromium), 2016/07/18 14:21:41]

assuming by empty you mean '', OK.

     self._build_dir = os.path.join(build_dir, options.target)
     if chromium_utils.IsWindows():
       self._tool_dir = os.path.join(self._chrome_dir, 'tools', 'build', 'win')
