OK.

Actually, extraclean would delete my backup files, so I didn't touch it.
Instead, the following recipe works for me:

    make maintainer-clean
    rm aclocal.m4 configure

.  I could make this into a new make target, say timetravel-clean.  :-)

Incidentally, I spotted a bug in lisp/Makefile, after noticing that one
of the *loaddefs.el files wasn't purged.  At lisp/Makefile.in, L78, we
have:

# Elisp files auto-generated.
AUTOGENEL = loaddefs.el \
        $(LOADDEFS) \
        cus-load.el \
        finder-inf.el \
        subdirs.el \
        ps-print-loaddefs.el \
        emacs-lisp/cl-loaddefs.el \
        calc/calc-loaddefs.el \
        eshell/esh-groups.el \
        cedet/semantic/loaddefs.el \
        cedet/ede/loaddefs.el \
        cedet/srecode/loaddefs.el \
        org/org-loaddefs.el \
        textmodes/reftex-loaddefs.el \
        mail/rmail-loaddefs.el \
        ibuffer-loaddefs.el \
        htmlfontify-loaddefs \             <============================
        emacs-lisp/eieio-loaddefs.el \
        dired-loaddefs.el

The third last entry is missing a ".el".  Should I just correct this in
the emacs-26 branch?
