bug#11302: Automake 1.11d on openSUSE 12.1

Sure:

==============================================================================

You can see:
  1. To avoid the libdir variable to be clobbered by this script, it is
     sufficient to pass a --libdir option.
  2. It is not possible to avoid the libexecdir variable modification.
     You can either live with it, or clobber it afterwards.
