I presume it comes from here (in mysql.inc):

  const
    mysqllib = 'libmysqlclient.'+sharedsuffix;
  {$IF DEFINED(mysql50)}
    mysqlvlib = mysqllib+'.15';
  {$ELSEIF DEFINED(mysql41)}
    mysqlvlib = mysqllib+'.14';
  {$ELSE}
    mysqlvlib = mysqllib+'.12';
  {$ENDIF}

This probably doesn't cover all the cases.  Assuming that a specific
client library can only talk to a specific server may also be wrong.
Debian testing also has libmysqlclient 16 and mysql-server 5.1.
