Details

Since Python 3.10 there's a hardcoded default list of openssl ciphers specified when initializing the SSL/TLS layer.

By adding `--with-ssl-default-suites=openssl` option to the `./configure` script, it allows Python to use the system-wide OpenSSL configuration, which is much more convenient. Especially regarding to SECLEVEL setting and problems reported by users, like:

The solution described above doesn't work in Arch because of hardcoded list of capabilities.

What was the rationale for adding this hardcoded list? This seems quite dangerous as increasing the systems-wide security level will not affect any python applications.
