    I'm using the same, but compile for arm:

    ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make O=../o_test allyesconfig
    ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make O=../o_test oldconfig

    in .config change to:
    # CONFIG_DYNAMIC_DEBUG is not set
    # CONFIG_DEBUG_INFO_REDUCED is not set

    ARCH=arm CROSS_COMPILE=arm-linux-gnueabi- make -j4 O=../o_test drivers/i2c/busses/


    Thanks,
    -- Christoph
