mkconfig: start deprecating Makefile config targets

Now that we've got boards.cfg and most people have converted over,
start warning people who have yet to so we can phase board configs
completely out of the Makefile.

+What:  boards with xxx_config targets in top level Makefile
+When:  Release v2012.03
+
+Why:   We have a boards.cfg file which the vast majority of boards have
+       converted over to.  Boards that still manually run mkconfig in the
+       top level Makefile are either dead, or the maintainer doesn't care,
+       or they are doing something weird/wrong that should be fixed in a
+       different way, or they need to extend boards.cfg syntax (unlikely).
+
+       In any case, if no one cares about these boards to figure out how
+       to make boards.cfg work, then we'll just punt them.
