Autoconf 2.65 and newer do not have the bug.  But packages still exist
where configure was generated with < 2.65, so these packages still have
the bug unless you either rerun newer autoconf, or pre-seed the cache.

This workaround is still necessary, as long as there are still packages
that don't run autoreconf and where configure was generated with a
too-old autoconf.
