It's really, really, really hard to believe that 7.4 libpq would emit
this.  The code looks like

            retry_ssl_read:
                    nread = recv(conn->sock, &SSLok, 1, 0);
                    if (nread < 0)
                    {
                        if (SOCK_ERRNO == EINTR)
                            /* Interrupted system call - just try again */
                            goto retry_ssl_read;

                        printfPQExpBuffer(&conn->errorMessage,
                                          libpq_gettext("could not receive server response to SSL negotiation packet:
%s\n"),
                        SOCK_STRERROR(SOCK_ERRNO, sebuf, sizeof(sebuf)));
                        goto error_return;
                    }

Are you sure your application isn't linked to an older (7.2) libpq?
The EINTR test wasn't there in 7.2.
