This happens when libunwind is configured with `-DLIBUNWIND_ENABLE_CROSS_UNWINDING=ON` passed to cmake.
Then https://github.com/llvm/llvm-project/blob/8faf2a0638d3e8d9411d55c3e5dfb7b452f35ca2/libunwind/CMakeLists.txt#L325-L328 does NOT enable `_LIBUNWIND_IS_NATIVE_ONLY`.
Then `#else // !_LIBUNWIND_IS_NATIVE_ONLY` block in `libunwind/include/__libunwind_config.h` is enabled and it contains (with changes from this patchset):

  # define _LIBUNWIND_TARGET_SPARC 1
  # define _LIBUNWIND_TARGET_SPARC64 1
