If you try to build a noarch metapackage on 64 bit machine, you'll end up with error like this:

RPM build errors:
    Installed (but unpackaged) file(s) found:
   /opt/rh/python27/root/lib64

This is caused by these lines in macros.scl:

%ifarch x86_64 ppc ppc64 sparc sparc64 s390 s390x
%{_scl_root}/%{_lib}
%endif

The problem is, that %ifarch conditionals seems not to expand in %files section. To reproduce this, just write a specfile with %files section like this:

%files
%ifarch <yourarch>
this_file_wont_be_searched_for
%endif

this_file_wont_be_searched_for doesn't exist in BUILDROOT, but RPM raises no error (so this could as well be RPM error, not scl-utils problem).

It'd seem that the same should happen to %{_scl_root}/usr/%{_lib}, which uses the same conditionals, but this is included because there are lots of other directories included inside it, which masks the error.
