make(1): rework memory allocation for the name of variables
There's more to know about variable names than fits in a one-liner.
While here, enforce that the name is not modified by splitting it into
the established (var + var_freeIt) pattern.
Since the name is not modified and not freed in the middle of evaluating
an expression, there is no need to make a backup copy of it. That code
had been necessary more than 12 years ago, but not anymore since the
code got a lot cleaner since then.
