Subject: [PATCH] configure: Add --disable-kvm-options

In Fedora, our qemu package is based on qemu-kvm, and we go to convoluted
lengths to provide a qemu-kvm binary with KVM on by default, but all
qemu-system-* with KVM off by default (using ./configure --disable-kvm)

For qemu-system*, what we really want is upstream qemu symantics of TCG
by default, but the opt in option for KVM. CONFIG_KVM_OPTIONS fits the
bill, so let's expose it through ./configure. This will also simplify
our packaging for non-x86 KVM.
