commit 07f8986051b5ad8f6f34b82036f615c70f7fbb3e
Author: Daniel Stenberg <address@hidden>
AuthorDate: Mon Nov 4 13:59:35 2019 +0100

    configure: only say ipv6 enabled when the variable is set
    
    Previously it could say "IPv6: enabled" at the end of the configure run
    but the define wasn't set because of a missing getaddrinfo().

    Fixes #4555
    Closes #4560
