title: Zlib and binascii don't build with Python3.6
body: <p>I've been trying to build Python3.6.1 from source code on Ubuntu 14.04. The sequence of commands is as recommended by README:</p>
  
  <pre><code>./configure
  make
  make test
  </code></pre>
  
  <p>The latter crashes because it cannot import binascii. In its output there is a following:</p>
  
  <pre><code>Following modules built successfully but were removed because they could not be imported:
  binascii              zlib 
  </code></pre>
  
  <p>Trying to skip <code>make test</code> and start <code>make install</code> I have it crashing after failing to import <code>zlib</code>. Some folks in the Ubuntu forums suggested to update all the zlib's packages from repositories. That doesn't help. How do I fix this?</p>
