This is a known issue with Autoconf 2.71 and later, see

  https://lists.gnu.org/archive/html/emacs-devel/2021-05/msg00130.html
  https://lists.gnu.org/archive/html/emacs-devel/2021-05/msg00187.html

My only recommendation is to downgrade back to an older version of
Autoconf.  I'm a happy user of 2.69.
