Bug description:Test case bug73594.phpt fails even when dns_get_record()
populates additional
Description:
------------
For PHP v8.0.2, Test case "Bug #73594 (dns_get_record() does not
populate $additional out parameter)
[ext/standard/tests/network/bug73594.phpt]" failed on SLES 12SP5, s390x.
I noticed that this TC is getting skipped on most distros for x86 and
s390x due to one or the other SKIPIF reasons.
For my case, I took a tcpdump to confirm that DNS response had values in
$additional. This was also confirmed by dig command but the TC is still
failing..
"php > var_dump(!empty($res) && empty($additional));" is expected to
return "bool(true)" but is returning "bool(false)".
Please refer below snapshot for result of dig command and the Test
case.. I can see that dns_get_record() is also returning value in
$additional.

Can you please give me a pointer to why this TC might be failing? Could
this be a bug in the test case or in php code?
Test script:
---------------
To reproduce:
php -f php-8.0.2/ext/standard/tests/network/bug73594.phpt
OR
You can run this to check all values on php shell:
<?php
$ret = 0;
exec("dig -tmx php.net +noall +additional 2>/dev/null", $out, $ret);
var_dump($ret);
$out = preg_grep("/^(?!($|;))/", $out);
var_dump($out);
$auth = array();
$additional = array();
$res = dns_get_record('php.net', DNS_MX, $auth, $additional);
// only check $additional if dns_get_record is successful
var_dump(!empty($res) && empty($additional));
var_dump($res);
var_dump($additional);
?>
Expected result:
----------------
The Test case should pass.
