Body: <p>Recently moved my CiviCRM install to a server running Debain 10 which brings:</p>
  <ul>
  <li>php7.3</li>
  <li>MariaDB 10.3.17</li>
  </ul>
  <p>Everything seems to be working fine, except that in the system checks I'm now seeing this error/warning:</p>
  <blockquote>
  <p><strong>PHP MySQL Driver (libmysqlclient)</strong></p>
  <p>It is recommended, though not yet required, to upgrade your PHP MySQL driver (libmysqlclient) to &gt;= 5.5.3 for utf8mb4 support.</p>
  </blockquote>
  <p>The check seems to get its info from <a href="https://www.php.net/mysqli_get_client_info" rel="nofollow noreferrer">mysqli_get_client_info</a> which on my server emits the following:</p>
  <pre><code>mysqlnd 5.0.12-dev - 20150407 - $Id: 7cc7cc96e675f6d72e5cf0f267f48e167c2abb23
  </code></pre>
  <p>This is surprising - 5.0?! What to do?</p>

Comments.Text: This came up in labs a few months ago but was resolved (https://lab.civicrm.org/dev/core/issues/1136). But I don't have any insight as to what's different here. Is there anything in that ticket that helps?

Title: CiviCRM on Debian 10 gives warning about PHP MySQL Driver (libmysqlclient)
ThreadText: # CiviCRM on Debian 10 gives warning about PHP MySQL Driver (libmysqlclient)
  
  (Asked by: username_0 on 2019-09-13)
  
  Recently moved my CiviCRM install to a server running Debain 10 which brings:
  
  php7.3
  MariaDB 10.3.17
  
  Everything seems to be working fine, except that in the system checks I'm now seeing this error/warning:
  
  PHP MySQL Driver (libmysqlclient)
  It is recommended, though not yet required, to upgrade your PHP MySQL driver (libmysqlclient) to >= 5.5.3 for utf8mb4 support.
  
  The check seems to get its info from mysqli_get_client_info which on my server emits the following:
  mysqlnd 5.0.12-dev - 20150407 - $Id: 7cc7cc96e675f6d72e5cf0f267f48e167c2abb23
  
  This is surprising - 5.0?! What to do?
