title: Makefile with multiples rules sharing same recipe
body: <p>I'd like to know if it's possible to write a Makefile with several rules, each one defining its own prerequisites and executing all of them the same recipe without duplicating the recipe. Example:</p>
  
  <pre><code>TARGETS= file1 file2 file3
  
  all: $(TARGETS)
  
  file1: dep1 dep2
  file2: dep2 dep3 dep4
  file3: dep2 dep1
      cat $^ &gt; $@
  </code></pre>
  
  <p>Thanks!</p>
