You are correct, core-avx-i may use instructions not available on the Sandy
Bridge.
But why shouldn't I be able to build Ivy Bridge optimised packages (for some
new desktop machines) on the (still much faster) Sandy Bridge server around?

I would expect to see this build error when using -march=native, but not when
setting a concrete target CPU to compile for.

I am happily admitting that this is not the most important bug in the world,
but still it is one :-)
