description:
Fixed build with --with-mail_ssl_module.

If nginx was compiled without --with-http_ssl_module, but with some
other module which uses OpenSSL (e.g. --with-mail_ssl_module), insufficient
preprocessor check resulted in build failure.  The problem was introduced
by e0a3714a36f8 (1.3.14).

Reported by Roman Arutyunyan.
