$NetBSD: patch-Makefile,v 1.1 2022/04/02 11:12:02 nia Exp $

* use gcc flags on SunOS
* for PKGSRC layout
* treat *BSDs same as FreeBSD.
* Use "ld -shared" rather than "ld --shared". The former allows cwrappers to
  detect shared lib link mode. This makes it omit "-pie" which would remove
  required symbols.
* Do not override LDFLAGS.
