Furthermore, configure should look for the industry standard "CI" environment variable to determine if it is running in a CI environment, and if so, select the ci build env as default. (This is supported e.g. by GHA).

There is no reason to run the failure handler at all unless you are running on a CI machine, so disabling the failure handler by default for developer build environments will fix this problem.
