After inspection of configure they are all brand new options I didn’t know
anything
about. That would have been —disable-{avx512f,avx512dq,avx512vl}. I am still

it enabled them without your compiler supporting it. The logic must be flawed.
In any case we need to add those to the list of disabled options in fat binary
builds.
It would have been nice to have the config log from when you had the failure.
