It seems I'm too late, but anyway... I had the exactly same problem before the proposed patch was applied, and it turned out the problem was VirtualBox wrongly reports CPU features. Changing `-march=native` to `-march=skylake` fixed the issue for me. The CPU (even inside VirtualBox) actually supports f16c and fma, but VirtualBox reports they aren't supported.
