python3: keep the order of patches and configure args stable - #3378
Merged
Conversation
`patches` and `configure_args` are deduplicated with `list(set(...))`, whose order depends on PYTHONHASHSEED. The configure arguments end up in the shipped `_sysconfigdata` module (CONFIG_ARGS), so two otherwise identical builds can differ, and the patches are applied in a different order on every run. Use an order-preserving dedup instead to help with reproducible builds. Upstreamed from https://github.com/spesmilo/python-for-android
