Note that code in ast_ssl_init would still call functions from
libssl1.0.2, even if compiled with OpenSSL 1.1.0 (but with the wrong
value for CRYPTO_num_locks(), 1 instead of 41). Or return -1 if
libssl.so.1.0.2 is not loaded.

(Though not running that code can be problematic if libssl1.0.2 is
not only loaded but actually used via some third library.)

And I suspect that OPENSSL_API_COMPAT is wrong value for conditional
compilation (it's not defined in OpenSSL 1.0.2 for example).
