    Android: Use unified toolchain in NDK r19+ · 97bca2f9
    Brad King authored
    The NDK build system now uses only a single toolchain in
    
        <ndk>/toolchains/llvm/prebuilt/<host>
    
    Its compilers are always `bin/{clang,clang++}` and its binutils are
    always `bin/<triple>-*`.  It is a standalone toolchain:
    
    * The Anrdoid API level is specified at the end of `--target=`.
    * The standard library may be specified via `-stdlib=`.
    * No need to pass system includes or libraries explicitly.
    * No need to pass `--sysroot` or `-gcc-toolchain`.
    
    Teach CMake to recognize NDK versions that have a unified
    toolchain with its own sysroot and use the above approach.
    
    Fixes: #18739
