Perhaps that could be achieved with a LOG_COMPILE definition which kicks
off a ‘wrapper-script’, as mentioned in
https://www.gnu.org/software/automake/manual/html_node/Parallel-Test-Harness.html,
which creates an environment for running an existing test/*/test-* shell
script, thereby avoiding altering them?

Just a guess, not based on any proper research or understanding.
