Clang and glibc are the official spellings, I think.

Icelake Client supports x86-64-v4 according to Intel ARK and a quick
test on a reference system.  Have you defined it differently in QEMU?

This one is correct.  Even though Knights Mill supports AVX-512, it does
not cover the variants that are considered definitive for x86-64-v4.

This one is a little bit odd.  Skylake Xeons which are not Xeon Scalable
Processors exist, and they do not support x86-64-v4.  Is this again a
matter of different naming in QEMU?
