Could you please move "check-block" to the beginning of the list
instead? I just noticed that the total runtime of "make check" will be
shorter that way when running the tests in parallel with "-j...".

Reason: check-block is the test with the longest runtime. So if the
other shorter tests are started first, they will occupy all CPUs for a
short amount of time, and check-block will be running more or less alone
in the end. Now if you start check-block first, it can run for the whole
time, while the shorter tests are scheduled to the remaining CPU jobs
instead.
