remove AC_REQUIRE from AU_DEFUN

Subject: remove AC_REQUIRE from AU_DEFUN

User-agent: Gnus/5.0808 (Gnus v5.8.8) Emacs/20.7

This is a followup to a bug report I sent to bug-autoconf@ in
April.  AC_REQUIRE cannot be called from the top-level (i.e.,
configure.ac itself), so it shouldn't be used in AU_DEFUN.
Otherwise autoupdate can produce a configure.ac that doesn't
compile.

        * lib/autoconf/specific.m4 (AC_CYGWIN, AC_EMXOS2, AC_MINGW32):
        Don't use AC_REQUIRE in AU_DEFUN.
