Apparently libtool cannot be installed separately from autoconf

and automake. Copying the files in $libtool/share/aclocal to 
$autoconf/share/aclocal does not work (and causes collisions when
installing the tools in the user environment). The solution seems to
be to install the three distributions in one single $out directory,
i.e., consider them as one package.
