I don't think it's harmless.  Stuff in /usr/lib/rpm uses $RPM_BUILD_ROOT
no matter what one does inside the specfile.

So if one installs into and otherwise deals with %{buildroot} inside the
spec, chances are that the scripts in /usr/lib/rpm will not operate on
the expected build root.

And if one uses $RPM_BUILD_ROOT everywhere in the specfile, things will
probably work just fine but having %{_target_cpu} in the buildroot
definition is useless for some cases.
