$NetBSD: patch-pylib_gyp_generator_make.py,v 1.4 2014/08/25 13:20:12 fhajny Exp $

Force platform libtool na Darwin, see
https://code.google.com/p/gyp/issues/detail?id=354&q=libtool

Also, don't try to use thin archives on NetBSD, they appear not to work
("ar t <archive>" says "Malformed archive").
