    tools: libtool: always install all auxillary files
    
    Remove the needless restriction
    for which auxillary files are installed.
    This aligns the behavior of libtoolize
    with the existing behavior of automake.
    
    This can prevent the seemingly random error
    if autoreconf happens to be ran multiple times:
    
      configure: error: cannot find required auxiliary files: compile
