the tests have all been compiled at this point using the check-build
target (separately) in order to split out test compile failures from
runtime failures, so use the check-TESTS target to run the tests without
checking whether the tests are built first

this adds a script to run make check after the build has finished,
repeating tests 3 times to try and reduce false positives from intermittent
failure tests
