--- Comment #6 from Luya Tshimbalanga luya@fedoraproject.org --- (In reply to Zbigniew Jędrzejewski-Szmek from comment #5)
The trick is to require some file which is only provided by glibc-devel.i686. E.g. BuildRequires: /usr/lib/crt1.o.
Now koji complains about missing /usr/include/gnu/stubs.h:10:11: fatal error: 'gnu/stubs-64.h' file not found on x86 architectures

Using %make_build CFLAGS="%{optflags}" LDFLAGS="%{__global_ldflags}" led to clang-3.8: warning: argument unused during compilation: '-specs=/usr/lib/rpm/redhat/redhat-hardened-ld' /usr/bin/ld: cannot find -lz clang-3.8: error: linker command failed with exit code 1 (use -v to see invocation)
