This is described in section 10.5.5 "Match-Anything Pattern Rules":

  One choice is to mark the match-anything rule as "terminal" by
defining it with a double colon.  <...>

  If you do not mark the match-anything rule as terminal, then it is
nonterminal.  A nonterminal match-anything rule cannot apply to a file
name that indicates a specific type of data.  A file name indicates a
specific type of data if some non-match-anything implicit rule target
matches it.
