This seems to be fixed with the libtool 2.4.6-4 Debian package
(and this doesn't seem to be due to a Debian patch)... or perhaps
the incorrect message was due to some old thing in some file (or
some other obscure reason): I no longer get the

  libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

message. And if I remove AC_CONFIG_MACRO_DIR([m4]) from configure.ac,
I get a correct message:

  libtoolize: Consider adding 'AC_CONFIG_MACRO_DIRS([m4])' to configure.ac,
  libtoolize: and rerunning libtoolize and aclocal.

Anyway, since I cannot reproduce the bug, I'm closing it.
