- Add PDO-support to php-oci8, so that it ships both
  /usr/lib/php5/20131226/oci8.so and /usr/lib/php5/20131226/pdo_oci8.so .

  This might be difficult: it seems the oci8-M.m.n.tgz does not offer PDO.
  The upstream full PHP sources do seem to; see
  http://php.net/manual/en/ref.pdo-oci.php .  We'd probably have to hack
  the Debian php source package...

  https://github.com/yajra/pdo-via-oci8 seems to be an implementation of PDO
  for Oracle in pure PHP.
