    rework machines to use dtb file in KERNEL_DEVICETREE variable
    
    The linux-dtb.inc has been rework to use the Linux kernel build system
    to generate the DeviceTree binaries so now KERNEL_DEVICETREE variable
    should has the /target/ name, not the file path.

    coreutils: fix the segfault issue of dd on e500v2 targets
    
    Since double-float is disabled for e500v2 targets build due to ICE
    of gcc-4.8.1, accordingly %Ld format of sprintf is disabled.
