test, which runs afoul of Automake installations where, for example, /usr/share/aclocal contains a copy of gl_THREADLIB. Problem reported by Sven Joachim in <http://lists.gnu.org/archive/html/emacs-devel/2011-07/msg00529.html>. This is just a quick temporary fix, specific to Emacs; I'll work with the other gnulib maintainers to get a more-permanent fix.
