The options is available since 3.10.0+ (https://github.com/python/cpython/pull/24820)
but has no effect until 3.11.0 (cpython b9e9292d75fdea621e05e39b8629e6935d282d0d)
and broken in MacOS until 3.12.2 (cpython cc13eabc7ce08accf49656e258ba500f74a1dae8),
we add downstream patches to fix that except for 3.11-dev where we disabled it
this checks if "no acceptable C compiler found" is in the last 10 lines of the log, and asks if the user has correctly installed the build dependencies.
provides a reliable way for Pyenv code to locate other parts of Pyenv code that are not under `PYENV_ROOT`

fixing the same problem:
We previously put the -isysroot switch only into CPPFLAGS, theorizing
that it was only needed to find the right copies of include files.
However, it seems that we also need to use it while linking programs,
to find the right stub ".tbd" files for libraries. We got away
without that up to now, but apparently that was mostly luck. It may
also be that failures are only observed when the Xcode version is
noticeably out of sync with the host macOS version; the case that's
prompting action right now is that builds fail when using latest Xcode
(12.2) on macOS Catalina, even though it's fine on Big Sur.
Specifically, the problem arises for `preadv' and `pwritev' (new in MacOS 11 Big Sur) when building with XCode 12.4 (supporting Big Sur) in MacOS 10.15 Catalina.
* Fix specifying XCode SDK for distutils
* Revert to preferring XCode Zlib
It turns out, everything since 2.7.12 and 3.5.2
can use libs from modern XCode SDK
which is always available unless we're using an alternate compiler
Zlib from XCode is virtually always present now so it only makes sense to use it from elsewhere if it's preferred.
Works around build failure for 2.7 that's incapable of using Zlib from XCode 7+ (see #3301)
* use `xcrun` instead of `xcodebuild` which is absent in CLT
* use an alternative way that's compatible with CPython's setup.py since 3.5.2
