Comment (by thomie):

 I think it would be confusing if `./validate --testsuite-only` didn't run
 the tests in the same way as `./validate`.

 Maybe one of the following solutions can serve you already? Instead of
 `./validate --testsuite-only`, run:
  * `make test THREADS=<n>`. It doesn't use the binary distribution.
 or
  * `./validate --no-clean`. It will call `make`, which should be a no-op,
 then recreate the binary distribution, and then call `make test
 BINDIST=YES` for you.
 or
  * `./validate --testuite-only --fast`. Drawback is that it doesn't run
 all tests.
