Hello Paul,

I have a question about your commit c331f0a:

A recipe (lets say linux_git.bb) has its PN in OVERRIDES with prefix 
'pn-' (pn-linux). So, if we have 'linux' in OVERRIDES then it cannot 
interfere. Should we search for pn-${PN} instead? E.g.:

     overrides = d.getVar('OVERRIDES', True).split(':')
     pn = d.getVar('PN', True)
     if ("pn-%s" % pn) in overrides:
         bb.warn('Recipe %s has PN of "%s" which is in OVERRIDES, this 
can result in unexpected behaviour.' % (d.getVar("FILE", True), pn))

Thanks,
Mikhail
