[BUG] breaks numpy in cross-compiling environment

setuptools version

setuptools >= 64.x

Python version

python 3.10.x

OS

Linux

Additional environment information

Environment is using the Synology DSM toolchain for cross-compiling for multiple archs (armv5, v7, v8, ppc, x64, i686).

Description

While preparing python 3.10.6 update I've took care to update all build requirements, including setuptools.
It hapens that it made numpy to fail to build starting with setuptools >= 64.x (also fails on 65.x).
Full build logs can be found here: https://github.com/SynoCommunity/spksrc/runs/7917533394?check_suite_focus=true
Associated SynoCommunity PR: https://github.com/SynoCommunity/spksrc/pull/5395

Expected behavior

numpy to build properly (like all other regular wheel being cross-compiled)

How to Reproduce

Can be reproduced easily using the SynoCommunity (spksrc) cross-compiling environment.

Output

Output is mostly hidden under pip call:

Start with the cross-compiling pip wheel command and the traceback ending in numpy/distutils/command/config_compiler.py and setuptools/command/sdist.py. Reproduce the numpy==1.22.4 build with setuptools 64.x or newer in the SynoCommunity environment; done means numpy builds successfully across the listed target architectures.
