    qemuboot.conf: make cpus match built artifacts
    
    Currently, the qemu CPUs for are specified as generic, but the built
    artifacts are not. For example, we build x86-64 artifacts targeting
    core2duo but run them in qemu with generic qemu/kvm CPUs. This causes
    some packages that take advantage of the host architecture to crash
    because they try to use CPU features not advertised by qemu. As an
    example, Qt uses ssse3. When artifacts linked against Qt and built
    targeting core2duo attempt to run on a generic qemu/kvm CPU, we get
    the following crash:
    
    Incompatible processor. This Qt build requires the following features:
         ssse3
    
    We could fix this by making packages like Qt not take advantage of CPU
    features. However, we will probably keep facing similar issues over
    time, so it's better to resolve them in a more enduring way.
    
    Fix this by making the qemu -cpu arguments match the built artifacts.
