Backporting LLVM's LLVM_USE_SPLIT_DWARF flag may fix this issue by preventing linking debug information into final binaries.
Summary: - Add `-gsplit-dwarf` as an option instead of a definition. - Only add that option on compilers supporting dwarf splitting, such as clang and gcc. Reviewers: echristo, pcc Subscribers: mgorny, aprantl, llvm-commits Tags: #llvm Differential Revision: https://reviews.llvm.org/D75328
