Subject: [PATCH 3/5] Extract extension ABI name resolvation code as helper
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

This commit introduces helper InterpreterConfig.get_python_target_env()
that can be used to determine the extension ABI python uses in
`ext_suffix` for this architecture.

Upstream-Status: Backport [https://github.com/PyO3/maturin/commit/fa64426f3a98a0455721c23ec86bd2240708b45e]
