Apple Clang 16 build issue, requires ld_classic #8653
Description
🐛 Describe the bug
When building from source with the new Apple Clang 16, I see the following error:
ld: multiple errors: duplicate LC_RPATH '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/cpuinfo-2023-11-04-4sylnhqsvndbdpgwvv3mydc6xhudikqh/lib' in '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/py-torch-2.4.1-wsy5qo376pu3gqk6sazvaff3wf6uo6fl/lib/python3.11/site-packages/torch/lib/libc10.dylib'; duplicate LC_RPATH '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/protobuf-3.13.0-sqetzfmrwohnuex4orfxr5loztdqj6rq/lib' in '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/py-torch-2.4.1-wsy5qo376pu3gqk6sazvaff3wf6uo6fl/lib/python3.11/site-packages/torch/lib/libtorch.dylib'; duplicate LC_RPATH '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/protobuf-3.13.0-sqetzfmrwohnuex4orfxr5loztdqj6rq/lib' in '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/py-torch-2.4.1-wsy5qo376pu3gqk6sazvaff3wf6uo6fl/lib/python3.11/site-packages/torch/lib/libtorch_cpu.dylib'; duplicate LC_RPATH '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/protobuf-3.13.0-sqetzfmrwohnuex4orfxr5loztdqj6rq/lib' in '/Users/Adam/spack/opt/spack/darwin-sequoia-m2/apple-clang-16.0.0/py-torch-2.4.1-wsy5qo376pu3gqk6sazvaff3wf6uo6fl/lib/python3.11/site-packages/torch/lib/libtorch_python.dylib'
clang++: error: linker command failed with exit code 1 (use -v to see invocation)
Current workaround is to inject -Wl,-ld_classic into the linker, but would be good to fix this as ld_classic is deprecated and will be removed in the future.
