    Require the OpenSSL 1.1 APIs when compiling ldns
    
    Moving the APIs from OpenSSL 1.1 supporting APIs to 3.x supporting APIs
    is a non-trivial effort. Require 1.1 API compatibility to unblock
    updating OpenSSL in base to 3.x.
    
    This mirrors what upstream has done in their configure.ac file.
