Subject: tests: Exit serial test runner gracefully when no tests are specified
X-Git-Url: http://git.lttng.org./?a=commitdiff_plain;h=a3ec5fe650e08aca7effc7e1c589ff7dcef79afe;p=lttng-tools.git

tests: Exit serial test runner gracefully when no tests are specified

This avoids the test failing when invoking make with `TESTS=xxx` to
limit which tests are run.
