Looking more closely, I wonder if the problem here is that `starred' isn't
getting reset.  This construction is effectively a switch statement, isn't it? 
I can't see why the presence of an `mcpu=generic-*` case ought to imply that
the default case should be treated as starred.  Perhaps `starred' should be
reset upon encountering a ';' character?
