However on the same host if you do:

There were always missing many %{?_isa} in BuildRequires, I was filing many of
them, got some fixed. But now it is even forbidden to use them:

IMO it is because it was causing more harm than good due to rpm/yum/dnf never
properly supporting those:
RFE: 'dnf builddep' should be able to extract the specfile from a .src.rpm and
use it for the dependencies

IIUC Fedora gave up on multi-arch building and you should use mock for that,
ISTM multi-arch is now officially supported only for installation.
