%ifarch note

[Tom Callaway]

Since I hit this, I'd imagine other people might.

If your package has:

BuildArch: noarch

It will set %{_target_cpu} to "noarch".

If you also use %ifarch in that spec file, you might be expecting it to
match %{_arch} (the architecture of the build server). It does not. It
matches %{_target_cpu}.

If you need to conditionalize on the value of %{_arch} in such a spec
file, you need to do it explicitly:

%if %{_arch} == x86_64 || %{_arch} == i686

Hope that helps other folks,
