Takes a path, and make it compatible with GNU Makefile format.
GNU make uses a weird quoting scheme for white space. A space or tab preceded by 2N+1 backslashes represents N backslashes followed by space; a space or tab preceded by 2N backslashes represents N backslashes at the end of a file name; and backslashes in other contexts should not be doubled.
