+Subject: [PATCH 1/7] python dependency: ensure that setuptools doesn't inject
+ itself into distutils
+
+We do not use setuptools for anything, and only lightly use distutils.
+Unpredictable issues can occur due to setuptools monkey-patching, which
+interferes with our intended use. Tell setuptools to simply never get
+involved.
+
+Note: while it's otherwise possible to check if the probe is run using
+sys.executable and avoid forking, setuptools unconditionally injects
+itself at startup in a way that requires subprocess isolation to
+disable.
+

+Subject: [PATCH 2/7] python module: stop using distutils schemes on
+ sufficiently new Debian
+
+Since 3.10.3, Debian finally started patching sysconfig with custom
+paths, instead of just distutils. This means we can now go use that
+instead. It reduces our reliance on the deprecated distutils module.
+
+Partial fix for #7702

+Subject: [PATCH 4/7] python module: stop using distutils "link to libpython"
+ probe on recent python
+
+On python >=3.8, this information is expected to be encoded in the
+sysconfig vars.
+
+In distutils, it is always necessary to link to libpython on Windows;
+for posix platforms, it depends on the value of LIBPYTHON (which is the
+library to link to, possibly the empty string) as generated by
+configure.ac and embedded into python.pc and python-config.sh, and then
+coded a second time in the distutils python sources.
+
+There are a couple of caveats which have ramifications for Cygwin and
+Android:
+
+- python.pc and python-config.sh disagree with distutils when python is
+  not built shared. In that case, the former act the same as a shared
+  build, while the latter *never* links to libpython
+
+- python.pc disagrees with python-config.sh and distutils when python is
+  built shared. The former never links to libpython, while the latter do
+
+The disagreement is resolved in favor of distutils' behavior in all
+cases, and python.pc is correct for our purposes on python 3.12; see:
+https://github.com/python/cpython/pull/100356
+https://github.com/python/cpython/pull/100967
+
+Although it was not backported to older releases, Cygwin at least has
+always patched in a fix for python.pc, which behavior is now declared
+canonical. We can reliably assume it is always correct.
+
+This is the other half of the fix for #7702
+
