You have to go searching in the test output for the aarch64-mcpu-native.c test. The bots run clang tests separately to llvm, with a lot of verbose output, which means the test that is failing might not be at the end of the output. It looks like it still has the same error message in the latest test run.

I think I see what is going on - you might have to make sure that the machine this runs on is AArch64 (and maybe linux), as getHostCPUName is ifdef'd per the host architecture. It will be difficult to test elsewhere.
