Dictionaries are not ordered in Python 3.5 and before, so building twice
in a row could lead to a different partition order, different
build/zephyr/include/generated/app_smem_*.ld files and different
binaries.
Fix with a minor change to the "for" loop in the output function:
make it iterate on sorted(partitions.items()) instead of the raw and
randomly ordered partitions dictionary.
It is easy to reproduce the issue even without downgrading to an
obsolete Python version; pick a test like samples/userspace/shared_mem/
and simply change the code to this:
--- a/scripts/gen_app_partitions.py
+++ b/scripts/gen_app_partitions.py
