title: Removing values from Make Variables
body: <p>Using GNU Make I want to remove values from a variable:</p>
  
  <pre><code>VAR := x.c y.c z.c
  &lt;snip&gt;
  VAR += x_x.c y_y.c
  </code></pre>
  
  <p>I now want to remove the "x.c" and "y.c" from the variable. I have tried using subst command but the x_x.c is removed as well.</p>
  
  <p>Are there any ways of doing this?</p>
  
  <p>The final variable should look like:</p>
  
  <pre><code>VAR = z.c x_x.c y_y.c
  </code></pre>
