Guess this is a Linux/Hurd/Fuchsia specific thing. I don't know much about the runtime build but I hope the hierarchy is not set in stone.

Can you dump a diff how `addPathIfExists(D, getStdlibPath(), Paths);` and a similar call will change `-L` paths in the linking stage?
You can use `clang ... '-###' |& sed -E 's/ "?-L/\n&/g; s/ "?-[iI]/\n&/g'` to break -L into multiple lines.
