configure/Make: Build libfdt from submodule DTC
Configure to use the DTC submodule to build libfdt when no system libfdt is found. Prompt to install the DTC submodule if --enable-fdt is set but no DTC can be found. DTC has no out-of-tree build capability, so the configure will symlink the Makefile and scripts directory in the out of tree build directory and pass in all the needed DTC arguments to make out of tree build happen. Ideally we fix the DTC make to support out of tree, but did it this way to avoid commits to DTC.
