Lets say you have BuildRequires: foo%{?_isa}. Koji makes the SRPM on a
ppc builder, so %{_isa} is evaluated as (ppc-32). The SRPM is then
handed to an x86_64 builder to build for x86_64, but it cannot meet the
BuildRequires because foo(ppc-32) is not found.
Okay... So if I now understand correctly, this doesn't involve Requires
at all.
I was never trying to address BuildRequires in this draft; but if folks
feel like the addition of the ${_isa} stuff for Requires warrants some
accompanying "don't do this for BuildRequires" prose, I'll add that.
