Subject: [PATCH] Use an explicit x86-64 cpu in tests that are sensitive to it
There are a few tests that depend on some target features **not** being
enabled by default, and usually they are correct with the default x86-64
target CPU. However, in downstream builds we have modified the default
to fit our distros -- `x86-64-v2` in RHEL 9 and `x86-64-v3` in RHEL 10
-- and the latter especially trips tests that expect not to have AVX.
These cases are few enough that we can just set them back explicitly.
