Cross compiling DTC compiler for ARM target

I need to use DTC on the running ARM target. I've got the sources for the DTC compiler by : git clone git://git.kernel.org/pub/scm/utils/dtc/dtc.git

Is there any way I can compile the dtc executable statically with cross compiler ?

I need DTC to analyze the device tree structure at runtime by using below command on target: dtc -I fs /sys/firmware/devicetree/base/

I've nfs mounted RFS. I can keep the dtc executable there to be used on target.

In buildroot 19.02. I can see the package dtc programs (BR2_PACKAGE_DTC_PROGRAMS) which install the dtc + some other tools (dtdiff, fdtdump, fdtget fdtput) on target. It depends on the library libfdt (BR2_PACKAGE_DTC), which also needs to be present on the target. (I dont know at which version it was added)

If you just want them in your nfs-mounted rootfs you could still build these packages in buildroot and then copy them manually.
