short-tests-0 were silently failing. I think because of the && make clean construction. Switch to ; instead.
Also fix all the test failures that were exposed.
`make all` is failing on CircleCI because it is missing Docker. Move that test
to GitHub actions, and switch the pedantic CircleCI test to `make allmost`.
Putting stack marking into every assembly files is required to indicate
that the stack does not need to be executable.
Executable flag on stack conflicts with some security measures, Systemd
MemoryDenyWriteExecute=yes for example.
