Only include custom OpenSSL ABI checks for OpenSSL 1.1
OpenSSL has a Policy on API compatibility in minor releases saying:
Only API additions are allowed in minor releases.
Minor releases are defined as 3.X.0. A change to 4.X.X would change the libssl.so.3 SONAME to libssl.so.4 so the (possibly) incompatible library would not get loaded in the first place.
This warning message is causing confusion between unrelated issues in the Arch Linux bug tracker.
