title: Conditional subdir-objects
body: <p>I have option <code>subdir-objects</code> set in <code>configure.ac</code>:</p>
  
  <pre><code>AM_INIT_AUTOMAKE([subdir-objects])
  </code></pre>
  
  <p>Is there any possibility to conditionally disable it in particular Makefiles (<code>Makefile.am</code>)?</p>
  
  <p>Thanks.</p>
