Arm64 fails with non clear reason

Builds hang, with output truncated mid-line

I localized the output truncation problem and reported it at Output is truncated heavily in ARM64 when a command hangs. It is indeed caused by a hanging command and only happens in Multi-CPU architecture environments, but the truncation happens long before the offending line. So currently, it’s only possible to identify the offending command by elimination.
