System: NetBSD yt 5.99.16 NetBSD 5.99.16 (YT) #4: Wed Sep 9 00:15:46 CEST 2009 root@yt:/archive/cvs/src/sys/arch/amd64/compile/obj/YT amd64

>Description:
There is no RTLD_NODELETE support on NetBSD.
totem would like to use it for the browser plugin, see
http://bugzilla.gnome.org/show_bug.cgi?id=583270

FreeBSD seems to support it, see
http://www.mail-archive.com/svn-src-all@freebsd.org/msg07076.html

>How-To-Repeat:
Try to build multimedia/totem-browser-plugin without totem/patches/patch-af.
>Fix:
Port from FreeBSD?

 Committed By:	skrll

 Added Files:

 Log Message:
 Add support for DF_1_BIND_NOW, DF_1_NODELETE and DF_1_NOOPEN marked
 objects, and the RTLD_NODELETE and RTLD_NOLOAD flags to dlopen(3).

 Mark libpthread as DF_1_NOOPEN and use it to test the functionality.

 Somewhat taken from FreeBSD.

 Fixes PR 42029.

 OK from christos and joerg.
