Why

The source-built ARM64 musl V8 archive references compiler runtime intrinsics. The target selector currently returns the unmerged base archive, leaving those symbols unresolved when the final release binary links.

What changed

Point the ARM64 musl target selection at the existing release archive that merges clang_rt.builtins with the V8 static library. Other platforms and V8 targets are unchanged.

Validation

  • bazel query //third_party/v8:rusty_v8_archive_for_target

The complete ARM64 musl link is exercised by #27326.

Stack: 5 of 6. Depends on #27324.
