A language can be added there (or the list of languages replaced) with 
the filter 'mce_spellchecker_languages'. It takes a string of comma 
separated "langname = locale", like this:

'+English=en,Danish=da,Dutch=nl,Finnish=fi'

The + indicated the default and the locale codes are ISO (only 2 
letters). More info:

Sample code:

<?php

add_filter( 'mce_spellchecker_languages', 'my_languages' );
function my_languages($str) {
   /*
   // add another
   $str .= ',Czech=cz';
   */

   // replace all
   $str = '+Czech=cz,English=en,German=de';

   return $str;
}
