Note that if ../1 or ../2 is a symlink to somewhere else, ../1/.. and
../2/.. aren't the same place.  It's the makefile's responsibility to
resolve any such aliasing, since make doesn't want the added complexity
(i.e. cost) by default but doesn't want to be wrong in the eccentric
case where symlinks are involved.
