There's nothing wrong :-).

Make evaluates left-to-right and completely expands each variable or
function it finds in the string before moving on to the next.

So, the first thing it needs to expand is $(eval $(change_value)) and
that sets VAR to 1.  Then it sees $(VAR) and expands that, which results
in "1".
