Just disabling it config side makes no difference.

I will try disabling it at configure time and see if it changes
anything, though I doubt it will.

Oh, and in case it is important, my fastcgi_params include
some extra options:

fastcgi_param  QUERY_STRING       $query_string;
fastcgi_param  REQUEST_METHOD     $request_method;
fastcgi_param  CONTENT_TYPE       $content_type;
fastcgi_param  CONTENT_LENGTH     $content_length;

fastcgi_param  SCRIPT_NAME        $fastcgi_script_name;
fastcgi_param  REQUEST_URI        $request_uri;
fastcgi_param  DOCUMENT_URI       $document_uri;
fastcgi_param  DOCUMENT_ROOT      $document_root;
fastcgi_param  SERVER_PROTOCOL    $server_protocol;
fastcgi_param  HTTPS              $https if_not_empty;
fastcgi_param  SSL_CIPHER          $ssl_cipher if_not_empty;
fastcgi_param  SSL_PROTOCOL        $ssl_protocol if_not_empty;
fastcgi_param  SSL_SESSION_ID      $ssl_session_id if_not_empty;
fastcgi_param  SSL_CLIENT_SERIAL   $ssl_client_serial if_not_empty;

fastcgi_param  SSL_CLIENT_I_DN     $ssl_client_i_dn if_not_empty;
fastcgi_param  SSL_CLIENT_CERT     $ssl_client_cert if_not_empty;
fastcgi_param  SSL_CLIENT_RAW_CERT $ssl_client_raw_cert if_not_empty;
fastcgi_param  SSL_CLIENT_VERIFY   $ssl_client_verify if_not_empty;

# disabled as requested
#fastcgi_param  GEOIP_COUNTRY_CODE $geoip_country_code;
#fastcgi_param  GEOIP_COUNTRY_NAME $geoip_country_name;

fastcgi_param  GATEWAY_INTERFACE  CGI/1.1;
fastcgi_param  SERVER_SOFTWARE    nginx/$nginx_version;

fastcgi_param  REMOTE_ADDR        $remote_addr;
fastcgi_param  REMOTE_PORT        $remote_port;
fastcgi_param  SERVER_ADDR        $server_addr;
fastcgi_param  SERVER_PORT        $server_port;
fastcgi_param  SERVER_NAME        $server_name;

# PHP only, required if PHP was built with --enable-force-cgi-redirect
fastcgi_param  REDIRECT_STATUS    200;
