retry after: #154485

Another solution for #154839

Prepare libLLVM.dylib and libLLVM-{version}{suffix}.dylib

How I verified it works. Let me know if it has wrong steps

  1. dist
./x.py dist rust-dev \
  --host=aarch64-apple-darwin \
  --target=aarch64-apple-darwin \
  --set llvm.download-ci-llvm=false \
  --set llvm.link-shared=true
  1. copy the tar to cache
cp build/dist/rust-dev-nightly-aarch64-apple-darwin.tar.xz \
  build/cache/llvm-116458d0a5ae01cd517cabd2d1aee7f5457018ab-false/rust-dev-nightly-aarch64-apple-darwin.tar.xz
  1. remove old ci-llvm if it exists
rm -rf build/aarch64-apple-darwin/ci-llvm
  1. Build
RUST_BACKTRACE=1 ./x build library -v
