Do we really need root for the test?

Again, why don't we rather pass the expected paths as the parameters to
the which_test function? For example:

which_test "-a" "programname" "$PWD/programname" $PWD/bin/programname"

Then we will do shift twice in the which_test() and loop over the rest
of the $@ doing grep in the temp for each iteration.
