title: Buildroot patches not applied for overriden package?
body: <p>I'm playing around with patches in Buildroot (version 2017.02), but when I override the package sources in <code>local.mk</code>:</p>
  
  <pre><code>PACKAGENAME_OVERRIDE_SRCDIR = /...path_to_local_checkout
  </code></pre>
  
  <p>I see that the Buildroot patches <strong>are not</strong> applied for this package.</p>
  
  <p>They are applied only if the package is not overriden in local.mk.</p>
  
  <p>Is this expected behavior?</p>

  <p>Notes:</p>
  
  <ul>
  <li>I didn't find the answer to my question in the Buildroot manual:
  <a href="https://buildroot.org/downloads/manual/manual.html#patch-apply-order" rel="nofollow noreferrer">https://buildroot.org/downloads/manual/manual.html#patch-apply-order</a></li>
  <li>The package I'm testing is the Linux kernel, but I guess it's unrelated.</li>
  <li>I put my patches in the global patch dir
  <code>board/company_name/common/patches/...</code></li>
  </ul>
