Actually the problem is that there is a pipeline wide timeout of 2 hours. This is reasonable most of the time but sometimes our AArch64 builds are taking > 2h. I will address this on our side.

Could that be due to a test taking ages, maybe, but probably not given we've had reports of this on other changes.

Also I was looking around and found https://buildkite.com/llvm-project/libcxx-ci/builds/67243/steps/canvas?sid=0198e5cb-a69a-43e1-944b-67d4402c4253 which looks exactly like the AIX failure seen on this PR.
