Indeed, "gnulib-tool --create-testdir" creates a configure.ac directly.
I'm changing it to allow AC_REQUIREs. But IMO the autoconf maintainers should
consider allowing AC_REQUIREs outside of functions (and in that case, the
inserted expansions should go into the current point).

* gnulib-tool (func_create_testdir): Wrap the set of autoconf snippets
in an AC_DEFUN. Needed so that the autoconf snippets can use
AC_REQUIRE.
