But the value of %_arch still changes, right?

I believe this will break things, like this:

| F	?= $(shell test ! -e /etc/fedora-release && echo 0; test -e /etc/fedora-release && rpm --eval %{fedora})
| ARCH	?= $(shell test ! -e /etc/fedora-release && uname -m; test -e /etc/fedora-release && rpm --eval %{_arch})
| MOCK_CFG	?= $(shell test -e /etc/fedora-release && echo fedora-$(F)-$(ARCH))
