title: installed shared library version number does not match LT_VERSION_INFO
body: <p>The libtool versioning number of a shared library is set in <code>configure.ac</code> via
  <code>
  LT_VERSION_INFO="lt_current:lt_revision:lt_age"
  </code>
  but when I set it to <code>0:1:0</code> <code>make install</code> installs the <code>lib..so.0.0.1</code>, and when I set it to <code>3:2:1</code> it installs <code>lib..so.2.1.2</code>. This does not seem right. If it is, can someone please explain what's going on? Otherwise, what could be wrong? The libtool version is 2.4.2.</p>
  
  <p>I am familiar with the fact libtool versions differ from release version. That is not the problem here.</p>
