It sounds like you may be building the old qemu-kvm.git source code.
Last year qemu-kvm.git was merged back into qemu.git.

It means you should use git://git.qemu-project.org/qemu.git if you are
building from source.

Some distros are creating transitional packages or wrapper scripts that
build QEMU (qemu-system-x86_64) and provide a /usr/bin/kvm or qemu-kvm
executable.
