<p>In the meanwhile I learned that flto=auto is not supported by any released gcc. We can't really go with such a value in rpm.</p>

<p>Yep, it will be supported first in GCC 10.1 release. For openSUSE, we're using a patched GCC compiler with the support. So I'm going to push the package to our <code>rpm</code> package.</p>
