Analyzed the build log, "-flto" is still not in the configure setting, is this expected? The full configure from here: http://download.eng.bos.redhat.com/brewroot/vol/rhel-9/packages/qemu-kvm/7.0.0/7.el9/data/logs/aarch64/build.log

I can see x86 enabled -flto: http://download.eng.bos.redhat.com/brewroot/vol/rhel-9/packages/qemu-kvm/7.0.0/7.el9/data/logs/x86_64/build.log, and I also compiled with -flto myself on aarch64, it passed. Steps refer to Eric's bug 2000479

So in my opinion, maybe we can also enable -flto on other architectures?

Anyway, the test result on the official build is passed.

Result: PASS as no Critical Regression or TestBlocker found
