[libmicrohttpd] FAIL: test_tls_options

[muradm]

Hello,

Building libmicrohttpd-0.9.73 under guix, and getting one test 
failed:

--8<---------------cut here---------------start------------->8---
$ ./src/testcurl/https/test_tls_options
curl version: libcurl/7.77.0 GnuTLS/3.7.2 zlib/1.2.11 
libidn2/2.3.1 nghttp2/1.44.0
The following handshake should fail (and print an error 
message)...
cURL failed to reject request despite SSL version mismatch!
TLS1.0 vs SSL3 test failed
$ echo $?
1
$
--8<---------------cut here---------------end--------------->8---

Any clue why this can happen?

Thanks in advance,
muradm
