  import gensim fails since updating to Xcode 7.3 
  I just updated my version of Xcode to 7.3. When I run `pip install --upgrade gensim` the process completed without any issues. However, when I try `import gensim` within the python shell the terminal barfs a bunch of C++ output with a block of execution errors that begins with: 
  
  `Exception: Compilation failed (return status=1): clang: error: unsupported option '-b mi2'. clang: error: unsupported option '-b mi'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-sse4a'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-tbm'. clang: error: unknown argument: '-target-feature'. clang: error: unknown argument: '-target-feature'....`
  
  I think this has something to do with where gensim is looking for its header files, but I'm somewhat at a loss. Any help debugging would be greatly appreciated.
