Hi,

on kirkstone branch when trying to build rust for raspberrypi machine
I'm getting:

ERROR: rust-cross-arm1176jzfshf-vfp-glibc-1.59.0-r0
do_rust_gen_targets: Error executing a python function in
exec_func_python() autogenerated:

The stack trace of python calls that resulted in this exception/failure was:

Exception: TypeError: int() argument must be a string, a bytes-like
object or a number, not 'NoneType'

by adding below it seems to fix an issue (copied from meta-rust):
