Order of strings in __static_attributes__ is not deterministic
Running the following a couple of times produces different hashes:
/opt/cpython/cross-build/build/python ../../Programs/_freeze_module.py zipimport ../../Lib/zipimport.py Python/frozen_modules/zipimport.h
sha256sum ./Python/frozen_modules/zipimport.hI patched this generator to output dis as follows:
