AFAIK `UNSUPPORTED: clang-19.0` would work. I'll double-check.

The Android libc++ CI uses a build of LLVM from the Android LLVM team itself because the ordinary Linux LLVM builds don't have the Android builtin archives, and the Android team doesn't use the official upstream LLVM release branches. I believe the issue is that release schedules don't line up? The android_llvm README has some comments about the Android LLVM release schedule, https://android.googlesource.com/toolchain/llvm_android/+/refs/heads/main#android-clang_llvm-toolchain.

In any case, the Android LLVM build also has a large number of cherry picks and local patches. (https://android.googlesource.com/toolchain/llvm_android/+/refs/heads/main/patches/).
