  subdir-objects: complain if it isn't enabled
  
  Since the next major automake version will make the behaviour so far
  only activated with the 'subdir-object' option mandatory, it's better
  if we start warning users not using that option.
  
  As suggested by Peter Johansson, we strive to avoid the warning when
  it would be irrelevant, i.e., if all source files sit in "current"
  directory.
  
  See automake bug#13378.
