title: Am I right that 'brew python install --universal' is gone?
body: <p>I'm in need of running some old wx stuff with python in 32-bit mode (<code>arch -i386 python wx.py</code>) under brewed python, macOS 10.12 will just give</p>
  
  <pre><code>arch -i386 python
  arch: posix_spawnp: python: Bad CPU type in executable
  </code></pre>
  
  <p>What's the easiest way forward? </p>
  
  <p>the macOS pre-installed one still works and I got the brew libraries working by symlinks <em>(there is probably a better approach)</em></p>
  
  <pre><code>sudo ln -s /usr/local/Cellar/wxpython/... /Library/Python/2.7/site-packages/wx
  
  arch -i386 /System/Library/Frameworks/Python.framework/Versions/2.7/bin/python
  </code></pre>
  
  <p>but I'd prefer an approach where I can rely on brew and pip</p>
  
  <p>I hope I'm just missing out on something obvious on how to get --universal support back using brew.</p>
