title: makefile: execute one target from another target plus additional commands
body: <p>I have a makefile with something like the following targets:</p>
  
  <pre>
  install:
      do a whole bunch of stuff to install
  
  dist: install
      cp README.txt $(INSTALL_DIR)
      zip $(INSTALL_DIR)
  </pre>
  
  <p>I am trying to not repeat the commands from target <code>install</code> and make <code>dist</code> execute <code>install</code> first before executing its own commands.</p>
  
  <p>Calling <code>make dist</code> does indeed execute all commands from target <code>install</code> but then just stops and it does not execute its own commands, e.g. the <code>cp</code>.</p>
  
  <p>Am I missing something?</p>
