Bug#213503: glibc: some GNU/KNetBSD fixes

[Robert Millan <zeratul2@wanadoo.es>]

Uhm.. seems like my patch is not complete. I still have to add netbsd-i386
to the rules.d / control.in dirs.

I have a few questions though:

 - Should the threads_archs variable in debian/rules.d/control.mk only include
   threaded platforms, where should non-thread platforms be?
 - Shouldn't GNU/Hurd be listed in threads_archs? (And nscd not sed'ed out in
   rules.d/control.mk)
 - It seems that the availability of nscd package is determined by the presence
   in threads_archs variable. Is that the intended?
