title: How does Bitbake handle 'inc' files in recipes
body: <p>I tried to find information how Bitbake handles 'inc' files (included by 'require') within recipes.  Unfortunately without success, maybe somebody can enlighten me.</p>
  <p>I want to move some common parts of custom recipes to an include file. To do this, it would be nice if I can access some variables assigned in the recipe in the include file. ( e.g. to do some concatenation ) and use the result in the recipe.</p>
  <p>Is this somehow possible ?</p>
