Trouble upgrading to 2.2.6a

[Alberto Luaces]

Hello,

I have recently updated my system, so now I have new versions of the 
Autotools:

autoconf 2.64-2  
automake 1:1.11-1
libtool 2.2.6a-4

I have a simple testcase where libtool fails to do the linking of a tiny 
executable, here is the process:

$ ls
configure.ac  Makefile.am  test1.c

$ autoreconf -vfi
autoreconf: Entering directory `.'
autoreconf: configure.ac: not using Gettext
autoreconf: running: aclocal --force
autoreconf: configure.ac: tracing
autoreconf: running: libtoolize --copy --force
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.
autoreconf: running: /usr/bin/autoconf --force
autoreconf: configure.ac: not using Autoheader
autoreconf: running: automake --add-missing --copy --force-missing
autoreconf: Leaving directory `.'

$ mkdir build && cd build
$ ../configure

[...] skipped configure output

$ ls
config.log  config.status  libtool  Makefile

$ make

I have searched on the web and it seems that the problem is a mismatch with 
the libtool templates. However, I haven't been able to find any outdated 
template on my system:

$ cd ..
$ aclocal --verbose 2>&1 | grep AC_PROG_LIBTOOL
aclocal: found macro _AC_PROG_LIBTOOL in /usr/share/aclocal/lt~obsolete.m4: 71  
     
aclocal: found macro AC_PROG_LIBTOOL in /usr/share/aclocal/libtool.m4: 102

$ dpkg -S /usr/share/aclocal/lt~obsolete.m4
libtool: /usr/share/aclocal/lt~obsolete.m4

$ dpkg -S /usr/share/aclocal/libtool.m4
libtool: /usr/share/aclocal/libtool.m4

How can I keep trying to know what is happening?
I'm attaching the small testcase.

Thank you,

Alberto
