@rprichard is working on moving all the architectures over to LLVM's unwinder (instead of the current case of only 32-bit Arm).

I'm guessing at a milestone here. Might get moved back, but unlikely to be moved up.

Merged into master. We still need to ensure that this gets to r23 though.

Add support for NDK r23.
e0a607a 
Context: https://github.com/android/ndk/wiki/Changelog-r23#changelog

The most important changes for Xamarin.Android:

NDK r23 removes GNU Binutils and so we need to switch to using our
bundled copy of them.

Upstream changes:

* Includes Android 12 APIs.
* Updated LLVM to clang-r416183b, based on LLVM 12 development.
  * [Issue 1047]: Fixes crash when using ASan with the CFI unwinder.
  * [Issue 1096]: Includes support for [Polly]. Enable by adding `-mllvm -polly`
    to your cflags.
  * [Issue 1230]: LLVM's libunwind is now used instead of libgcc for all
    architectures rather than just 32-bit Arm.
  * [Issue 1231]: LLVM's libclang_rt.builtins is now used instead of libgcc.
  * [Issue 1406]: Fixes crash with Neon intrinsic.
* Vulkan validation layer source and binaries are no longer shipped in the NDK.
  The latest are now posted directly to [GitHub](https://github.com/KhronosGroup/Vulkan-ValidationLayers/releases).
* Vulkan tools source is also removed, specifically vulkan_wrapper.
  It should be downloaded upstream from [GitHub](https://github.com/KhronosGroup/Vulkan-Tools).
* The toolchain file (android.toolchain.cmake) is refactored to base on CMake's
  integrated Android support. This new toolchain file will be enabled by default
  for CMake 3.21 and newer. No user side change is expected. But if anything goes
  wrong, please file a bug and set `ANDROID_USE_LEGACY_TOOLCHAIN_FILE=ON` to
  restore the legacy behavior.
    * When using the new behavior (when using CMake 3.21+ and not explicitly
      selecting the legacy toolchain), **default build flags may change**. One
      of the primary goals was to reduce the behavior differences between our
      toolchain and CMake, and CMake's default flags do not always match the
      legacy toolchain file. Most notably, if using `CMAKE_BUILD_TYPE=Release`,
      your optimization type will likely be `-O3` instead of `-O2` or `-Oz`. See
      [Issue 1536] for more information.
* [Issue 929]: `find_library` now prefers shared libraries from the sysroot over
  static libraries.
* [Issue 1390]: ndk-build now warns when building a static executable with the
  wrong API level.
* [Issue 1452]: `NDK_ANALYZE=1` now sets `APP_CLANG_TIDY=true` rather than using
  scan-build. clang-tidy performs all the same checks by default, and scan-build
  was no longer working. See the bug for more details, but no user-side changes
  should be needed.

Add support for NDK r23.
38600a3 
Context: https://github.com/android/ndk/wiki/Changelog-r23#changelog

The most important changes for Xamarin.Android:

NDK r23 removes GNU Binutils and so we need to switch to using our
bundled copy of them.

Upstream changes:

* Includes Android 12 APIs.
* Updated LLVM to clang-r416183b, based on LLVM 12 development.
  * [Issue 1047]: Fixes crash when using ASan with the CFI unwinder.
  * [Issue 1096]: Includes support for [Polly]. Enable by adding `-mllvm -polly`
    to your cflags.
  * [Issue 1230]: LLVM's libunwind is now used instead of libgcc for all
    architectures rather than just 32-bit Arm.
  * [Issue 1231]: LLVM's libclang_rt.builtins is now used instead of libgcc.
  * [Issue 1406]: Fixes crash with Neon intrinsic.
* Vulkan validation layer source and binaries are no longer shipped in the NDK.
  The latest are now posted directly to [GitHub](https://github.com/KhronosGroup/Vulkan-ValidationLayers/releases).
* Vulkan tools source is also removed, specifically vulkan_wrapper.
  It should be downloaded upstream from [GitHub](https://github.com/KhronosGroup/Vulkan-Tools).
* The toolchain file (android.toolchain.cmake) is refactored to base on CMake's
  integrated Android support. This new toolchain file will be enabled by default
  for CMake 3.21 and newer. No user side change is expected. But if anything goes
  wrong, please file a bug and set `ANDROID_USE_LEGACY_TOOLCHAIN_FILE=ON` to
  restore the legacy behavior.
    * When using the new behavior (when using CMake 3.21+ and not explicitly
      selecting the legacy toolchain), **default build flags may change**. One
      of the primary goals was to reduce the behavior differences between our
      toolchain and CMake, and CMake's default flags do not always match the
      legacy toolchain file. Most notably, if using `CMAKE_BUILD_TYPE=Release`,
      your optimization type will likely be `-O3` instead of `-O2` or `-Oz`. See
      [Issue 1536] for more information.
* [Issue 929]: `find_library` now prefers shared libraries from the sysroot over
  static libraries.
* [Issue 1390]: ndk-build now warns when building a static executable with the

[build] Add support for NDK r23. (#6073)
f361d99 
Context: https://github.com/android/ndk/wiki/Changelog-r23#changelog

The most important changes for Xamarin.Android:

NDK r23 removes GNU Binutils and so we need to switch to using our
bundled copy of them.

Upstream NDK r23changes:

  * Includes Android 12/API-31 APIs.

  * Updated LLVM to clang-r416183b, based on LLVM 12 development.
    * [Issue 1047]: Fixes crash when using ASan with the CFI unwinder.
    * [Issue 1096]: Includes support for [Polly].
      Enable by adding `-mllvm -polly` to your cflags.
    * [Issue 1230]: LLVM's `libunwind` is now used instead of `libgcc`
      for all architectures rather than just 32-bit ARM.
    * [Issue 1231]: LLVM's `libclang_rt.builtins` is now used instead
      of `libgcc`.
    * [Issue 1406]: Fixes crash with Neon intrinsic.

  * Vulkan validation layer source and binaries are no longer shipped
    in the NDK.  The latest are now posted directly to
    [KhronosGroup/Vulkan-ValidationLayers].

  * Vulkan tools source is also removed, specifically `vulkan_wrapper`.
    It should be downloaded upstream from [KhronosGroup/Vulkan-Tools].

  * Refactored the toolchain file `android.toolchain.cmake`, basing
    it on CMake's integrated Android support.  This new toolchain file
    will be enabled by default for CMake 3.21 and newer.
    No user side change is expected.  But if anything goes wrong,
    please file a bug and set `ANDROID_USE_LEGACY_TOOLCHAIN_FILE=ON`
    to restore the legacy behavior.
      * When using the new behavior (when using CMake 3.21+ and not
        explicitly selecting the legacy toolchain),
        **default build flags may change**.  One of the primary goals
        was to reduce the behavior differences between our toolchain
        and CMake, and CMake's default flags do not always match the
        legacy toolchain file.  Most notably, if using
        `CMAKE_BUILD_TYPE=Release`, your optimization type will likely
        be `-O3` instead of `-O2` or `-Oz`.
        See [Issue 1536] for more information.

  * [Issue 929]: `find_library` now prefers shared libraries from the
    sysroot over static libraries.

  * [Issue 1390]: `ndk-build` now warns when building a static
    executable with the wrong API level.

  * [Issue 1452]: `NDK_ANALYZE=1` now sets `APP_CLANG_TIDY=true` rather
    than using `scan-build`.  `clang-tidy` performs all the same checks
    by default, and `scan-build` was no longer working.
    See [Issue 1452] for more details; no user-side changes should
    be needed.
