Log Message:
make(1): clean up PrintVar

Conceptually, the last parameters of Var_Subst and Var_Value differ a
lot.  The former is the actual variable value while the latter is just a
pointer to be freed.  It will be changed to a void pointer in a few
commits.

To keep the number of needed variables small and the code simple, the
printf statement is mentioned in each branch.  An additional benefit is
that in 2 of the 3 branches, no null pointer can occur.
