I think we also need a change to the qemu-kvm.spec file to enable LTO on non-x86 again. There's a hack there at the top of the file that looks like this:
Without removing that, we don't get LTO on s390x and aarch64, so I think this cannot properly verified. @stefanha, could you add such a patch on top, please?

%ifnarch x86_64
%global _lto_cflags %%{nil}
%endif
