Description: stop linking against libmysqlclient_r and link directly against libmysqlclient instead
 Quoting from Debian's bugreport #825086:
 .
  Your package currently links against libmysqlclient_r. libmysqlclient_r
 was the thread-safe version of libmysqlclient in previous MySQL
 releases. However, libmysqlclient has been itself been made thread-safe
 since before the current libmysqlclient18. Thus libmysqlclient_r is
 currently deprecated and provided as a compatibility symlink only, and
 will disappear in MySQL 5.7. This change can be made now, in advance of
 a possible future transition to libmysqlclient20, which does not provide
 the _r variant.
 .
 In Ubuntu, we have done this with the attached quilt patch, which I
 believe is also applicable to Debian.
