Some tests expect to be compiled for a specific CPU or require certain target features to be present (or absent). These tests work fine with default CPUs but fail in downstream builds for RHEL and Fedora, where we use non-default CPUs such as z13 on s390x, pwr9 on ppc64le, or x86-64-v2/x86-64-v3 on x86_64.
