crypt module might need libcrypt #98895
Description
Bug report
On some platforms, e.g. NetBSD, building _crypt module needs linking against libcrypt. It semms like libcrypt detection has been removed from Python 3.11.0's setup.py, while still present in Python 3.10.8.
Your environment
- CPython versions tested on: 3.11.0
- Operating system and architecture: NetBSD 9.2, NetBSD-current
Fix
I copied the appropriate section of setup.py from Python 3.10.8, and now the building works correctly.
