    config: x86: stop pretending to be an Lguest guest
    
    Ever since v2.6.36 there's a conflict between OLPC support and Lguest
    guest support: a kernel image can't both support booting OLPC x86
    hardware and booting as an Lguest guest. Booting a kernel image that
    tries to do both as an Lguest guest will fail with
        lguest: Reinjecting trap 13 for fault at 0x1000062: Invalid argument
    
    This means that people wanting to boot an Lguest guest on 32 bits x86
    needed to build their own kernel image without OLPC support since, it
    seems, Fedora 15. So let's stop pretending to support being an Lguest
    guest. People wanting to have that will now not only have to disable
    CONFIG_OLPC but also enable CONFIG_LGUEST_GUEST.
    
    (A second order effect is that both CONFIG_VIRTIO and
    CONFIG_VIRTIO_CONSOLE will change from 'y' to 'm' in our builds.
    Assuming a sane build system no one should notice. We'll see.)
