commit 727560e6011efcb36d2f3ac6910444bc775abaa1
Author: Darren Tucker <dtucker at dtucker.net>
Date:   Tue Mar 28 18:06:42 2023 +1100

    Prevent conflicts between Solaris SHA2 and OpenSSL.
    
    We used to prevent conflicts between native SHA2 headers and OpenSSL's
    by setting OPENSSL_NO_SHA but that was removed prior to OpenSSL 1.1.0
