title: Multi-line bash commands in makefile
body: <p>Considering that every command is run in its own shell, what is the best way to run a multi-line bash command in a makefile? For example, like this:</p>
  <pre><code>for i in `find`
  do
      all=&quot;$all $i&quot;
  done
  gcc $all
  </code></pre>
