automake-1.11.x: create symlinks for un-versioned directory names

The latest Automake version installs the 'aclocal' and 'automake' directories
with a '-1.11' version suffix. Our setup hook is not prepared to handle that,
so we add those symlinks as a quick fix. A better solution would be to extend
the setup hook for Automake to recognize those kind of version suffixes.
