gdb moxie build failure

Hi

gdb on the head has moxie-rtems fail like this:

echo "/* generated by Makefile */" > tmp-hw.h
/bin/sh ../../../binutils-gdb/sim/moxie/../common/create-version.sh
../../../binutils-gdb/sim/moxie/.. x86_64-unknown-linux-gnu
moxie-rtems4.11 version.c
sim_hw=""; \
for hw in $sim_hw ; do \
  echo "extern const struct hw_descriptor dv_${hw}_descriptor[];" ; \
done >> tmp-hw.h
dtc -O dtb -o moxie-gdb.dtb ../../../binutils-gdb/sim/moxie/moxie-gdb.dts
make[3]: dtc: Command not found
echo "const struct hw_descriptor *hw_descriptors[] = {" >> tmp-hw.h
make[3]: *** [moxie-gdb.dtb] Error 127
make[3]: *** Waiting for unfinished jobs....
sim_hw=""; \
for hw in $sim_hw ; do \

Is dtc a required tool that is not checked for? Is the output in the tree
but not timestamped? maintainer only tool?

Thanks.
