The AOSP clang toolchain uses the new layout+names for targeting linux but hasn't migrated for compiler-rt libs targeting Android.  See https://android.googlesource.com/platform/prebuilts/clang/host/linux-x86/+/refs/heads/main/clang-r510928/lib/clang/18/lib/linux/ for `-android-`.

Will post an estimate on this migration but I expect it to be in the order of months rather than weeks.
