Hi,
While working on the "reproducible builds" effort [1], we have noticed
that py-lmdb could not be built reproducibly.
The attached patch removes randomness from the build system by ensuring
_config.py is written in a deterministic order instead of based on the
the serialised dict order.
Once applied, py-lmdb can be built reproducibly in our reproducible
toolchain.
