[issue43724] macOS cannot compute sizeof (long double)

[Ned Deily]

New submission from Ned Deily <nad at python.org>:

>From the config.log you supplied, it looks the macOS system you are running on was upgraded to the current latest version, 11.2.3, but the Command Line Tools were not. It seems that with recent macOS releases, you often need to do that manually for each bugfix release.  Try:

  xcode-select --install

If successful, you should see currently:

  cc --version
     Apple clang version 12.0.0 (clang-1200.0.32.29)
