Add basic support to run m68k under QEMU via kunit_tool.

Does this need CONFIG_VIRTIO_CONSOLE=y? It seems to work fine without.

drivers/clk/.kunitconfig:

    Fails because m68k uses big-endian I/O ops

drivers/gpu/drm/tests/.kunitconfig

    kernel BUG at drivers/gpu/drm/drm_buddy.c:21!
    (also on arm, ignored)

drivers/gpu/drm/vc4/tests/.kunitconfig

    Depends on arm, works on arm

drivers/hid/.kunitconfig

    Unable to handle kernel NULL pointer dereference at virtual address (ptrval)
    Oops: 00000000
    PC: [<001d7380>] uclogic_params_ugee_v2_has_battery+0x6/0x68
    (also on arm, ignored)

fs/ext4/.kunitconfig: OK

fs/fat/.kunitconfig: OK

kernel/kcsan/.kunitconfig

    Needs HAVE_ARCH_KCSAN and SMP
    (the former also on arm, ignored)

lib/kunit/.kunitconfig: OK

mm/kfence/.kunitconfig

    Needs HAVE_ARCH_KFENCE
    (fails on arm due to missing CONFIG_KFENCE_KUNIT_TEST=y, which
    depends on TRACEPOINTS)

net/sunrpc/.kunitconfig

    After dropping CONFIG_STACKTRACE=y (why is this needed?) from
    net/sunrpc/.kunitconfig:
    Unable to handle kernel NULL pointer dereference at virtual address (ptrval)
    (also on arm, ignored)
