Sorry, I didn't notice the ping until just now.
The CMake feature testing seems broken, on Android at least. Here's a
representative error from
`build/android-ndk-21-def-x86/CMakeFiles/CMakeError.log`:
```
Performing C++ SOURCE FILE Test CXX_SUPPORTS_NOSTDLIBXX_FLAG failed with the
following output:

```
It's trying to see if `-nostdlib++` is supported, but I don't see that flag
being passed in the `clang++` command line that CMake uses. In any case, CMake
tries to build a C++ program, which fails because libc++ doesn't exist yet.
It seems that the Android support in the Dockerfile is broken after a refactor
last year. I have some changes that get it working again. BuildKite is still
successfully running Android tests as of today, so I think it's using an old
image.
