 The fix for #5771 is still not right.  If the error_log setting in php.ini
 is empty (the default), errors should still be logged.  (See
 http://www.php.net/manual/en/errorfunc.configuration.php#ini.error-log.)
 But in this case, ini_get('error_log') returns an empty string, so the
 iswritable check in wp-includes/wp-db.php line 935 (WordPress 3.4) fails
 and nothing is logged.  Probably, there should be an test for empty string
 just as there is for 'syslog'.

 Patch attached.
