Bug description:
  ==================================
  Impact: libfdt-dev is unusable
  Fix: we use the patch from debian wheezy to export the needed .h file.
  Test case: download qemu package from trusty, remove the "<< 1.4.0" versioning from the libfdt-dev dependency, and try to build
  Regression Potential there should be none, we simply export another .h file.
  ==================================

  The configure scripts checks for fdt by looking at libfdt_env.h

  configure:2610: #include <libfdt_env.h>

  This file only exists in libfdt-dev version 1.4.0 and onwards, so it makes sense to specify build-dependency on that version. Otherwise, configure fails with:
      error_exit "DTC not present. Your options:" \
          "  (1) Preferred: Install the DTC devel package" \
          "  (2) Fetch the DTC submodule, using:" \
          "      git submodule update --init dtc"
