That is the case on x86 as well, -march=native -mtune=znver5 will
still tune for znver5, but -march=native will tune for native.

-march=native implies -mtune=native so I think the latter is redundant.

This makes sense to me, and the documentation is fine (with "latter"
instead of "later"); I cannot approve the code
