In the normal case, one does, e.g.,
make TEST="cat" test
This means that the value of EXES in the Makefile contains all
possible targets, which means many prerequisites that aren't
required get built.
With this change, when the `test` target is in effect (and,
in particular, *only* the test target), then the value of
EXES is ignored when calculating dependencies. Otherwise,
the values of EXES and TESTS are both considered.
