I am on a non-x86 platform, do have the X86 backend built, but realised that I am not running those test when I develop locally, so that was a little lesson learned.

Yeah, those tests are nice to have to test the execution flow, but definitely run extremely sparingly. You need to be on Linux with perf counter access, and quite a few of the bots are virtualized which prevents perf counter access.
