Avoid 'make clean' producing an 'rm' command which has a lot of duplicate 'hw//*.o' arguments, by using $(sort $(dir ..)) rather than $(dir $(sort ..)) so Make's sort function will remove the duplicates for us. We can also remove the double '//' safely because $(dir ..) is guaranteed to return a string ending in '/'.
