title: Using curly brackets for variable expansion in makefile doesn't work
body: <p>When I run below command on shell, it works properly. but if I write it in a Makefile and call it with "make" command it doesn't work.</p>
  
  <blockquote>
    <p>cp wpa_{cli,supplicant,passphrase,event} /usr/local/bin/</p>
  </blockquote>
  
  <p>error after "make" command:</p>
  
  <blockquote>
    <p>cp: cannot stat `wpa_{cli,supplicant,passphrase,event}': No such file
    or directory</p>
  </blockquote>
  
  <p>What can i do to make it work with Makefile? I use Ubuntu 12.04. Same Makefile works on other linux distributions.</p>
