I find it overkill to move one line of define() to an include file. A
possible way to comply with PSR1 in this situation would be the following.

In js/whitelist.php, replace the define() with
$pmaMinimumCommon = true;

In libraries/common.inc.php replace the if (! defined()) with
if (! pmaMinimumCommon)
