Description of problem:
Compilation of the source code of 6.1.1 and 6.2.0 fails in the qemu-system-ppc target ath the linking stage. Specifically the error in both cases is 
usr/lib/gcc/x86_64-pc-linux-gnu/9.2.0/../../../../x86_64-pc-linux-gnu/bin/ld: libqemu-ppc-softmmu.fa.p/hw_ppc_vof.c.o: in function `vof_build_dt':
/home/silviu/qemu-work/qemu-6.1.1/build/../hw/ppc/vof.c:1033: undefined reference to `fdt_get_max_phandle'
