Log Message:
make(1): add test for intentional hash collision for variable names

Hash collisions may slow down make in certain special situations.  There
is no point though in maliciously triggering such a situation since
anyone who can inject values into makefiles can easily run shell
commands using the :!cmd! modifier or similar mechanisms.  Crafting
variable names just to slow down make is thus not an attack vector.
