Xcode project does not link with homebrew LLVM

All other steps seem to work fine but linking fails. All steps from instructions were followed. Here's snippet of linker error:

Undefined symbols for architecture arm64:

Research shows points to this being due to gcc compiling included libs with stdlib and apple clang not. How is this resolved?

Was this resolved? I've run into this error as well, if you were able to solve it I'd love to know!
