I tried again:

1.

No m4 directory, no AC_CONFIG_MACRO_DIR([m4]) in configure.ac, no 
ACLOCAL_AMFLAGS in Makefile.am, running autoreconf:

Everything works, except libtool suggests:

libtoolize: Consider adding `AC_CONFIG_MACRO_DIR([m4])' to configure.ac and
libtoolize: rerunning libtoolize, to keep the correct libtool macros 
in-tree.
libtoolize: Consider adding `-I m4' to ACLOCAL_AMFLAGS in Makefile.am.

2. If I do _exactly_ this:

diff --git a/configure.ac b/configure.ac
index 6e2051f..dd1cb85 100644
--- a/configure.ac
+++ b/configure.ac

 .SILENT:

+ACLOCAL_AMFLAGS = -I m4
 export AM_LIBTOOLFLAGS = --silent

The next run of autoreconf fails with:

aclocal: couldn't open directory `m4': No such file or directory
autoreconf: aclocal failed with exit status: 1


So it seems to me libtoolize suggests something that breaks the system.
