Complete build log

Is this about time-outs again? Is our build machine too slow again?

CPython versions tested on:

3.15

Operating systems tested on:

Linux

Commencez par Lib/test/test_os/test_os.py, au niveau de TimerfdTests.test_timerfd_ns_poll et de check_timerfd_poll, puis consultez le journal de build associé et reproduisez le problème sous Linux s390x. Le travail est terminé lorsque la raison pour laquelle le nombre de polls est de 2 au lieu de 1 a été identifiée et que le test en échec est résolu.
