  "make test" executes "run-tests.php" script with "php" binary.  Some
 test scripts such as session must be executed by CGI SAPI. Therefore,
 you must build PHP with CGI SAPI to perform all tests.

-SAPI. Tests that may not executed by CLI SAPI will be skipped.

 executing test scripts may differ. If you use different PHP binary for
 executing "run-tests.php" script, you may get errors.
