This variable has been provided since commit746906242d(Android: Detect NDK version number, 2021-02-26, v3.20.0-rc3~1^2~3) when using CMake's NDK support or the modern NDK toolchain file. Since commit005e2cdfb0(Android: Do not use gold for ndk >= r22, 2021-02-26, v3.20.0-rc3~1^2) we need the value in our compiler/platform information files, so provide it when using the NDK legacy toolchain file too. Revert commit1c86e397fe(Android/Clang: Tolerate undefined CMAKE_ANDROID_NDK_VERSION, 2022-09-16, v3.25.0-rc1~118^2) since the variable should now always be defined. Issue: #21772 Fixes: #24386
