If I understand the problem correctly, the root of the problem is that yocto
"degrades" to i686.

When I set DEFAULTTUNE to i586 for a 64bit machine I'd expect
TARGET_SYS still being x86_64-poky-linux.
But it is i686-poky-linux.

Sure, let me trigger a rebuild, currently my yocto is in limbo-state. :)
So might take some time.
