   Log Message:
   syslog-ng overloads sigaction() with its own version, and calls the libc
   sigaction() with a dlsym call. On NetBSD this ends up calling the compatibility
   sigaction() which fails with ENOSYS if COMPAT_13 is not in the kernel.
   Even with COMPAT_13 it would be incorrect because we call the compat
   sigaction() with the non-compat arguments.

   On NetBSD, fix this by calling explicitely __libc_sigaction14().
   Bump PKGREVISION

$NetBSD: patch-lib_signal-handler.c,v 1.1.2.2 2019/03/17 15:45:44 bsiegert Exp $
sigaction() is the old, compat syscall. On NetBSD call the up to date one.
