genin:
 * reimplement the logic what is considered to be a package. From now on every directory containing a file named Config.in is considered to be a package directory. This is not the best logic, it's however consistent with the logic implemented [source:trunk/Makefile?rev=11076#L145 here]. The new logic makes it possible to create pseudo-packages containing just one file - either ${pkg}.mk or Config.in (useful in some cases). The old logic caused make to stuck in infinite loop in these cases.
 * refs #1269
