Commitd36e945changed findleaves.py to sort the output files so that the order is deterministic and won't cause spurious build errors when files happen to be listed (and hence read) in different order on e.g. add/remove the makefiles. This correction broke after commit4820a94because the conversion to a set with set() in order to remove duplicates came after sort() and potentially altered the order of the elements. This commit fixes makes sure findleaves.py is guaranteed to return a sorted filename list without duplicates. Change-Id: Ifd96d04d45641fe43d4cc4739f78a2d4d25cc212
