$NetBSD: patch-configure,v 1.1 2023/09/13 07:36:44 taca Exp $

* More support for OpenSSL 1.1; not only check SSL_Library_init() but
  also check OPENSSL_init_ssl().
* Fix syntax error by accidental new line.
* Utilize <stdlib.h> on BSD.
* Do not override CFLAGS/CXXFLAGS except linux.
* Prevent WRKDIR reference.
