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.
