271855, 271856 or 271857 seem to have broken the Polly parallel build.

This was just a buildbot configuration problem. After the cmake update I restarted the buildbot and accidentally overwrote the export OMP_NUM_THREADS=2 setting that ensured that not too many threads are run in parallel. As a result, the execution time increased for the individual test cases and we run into timeouts.
