When using Clang with a bare-metal triple, -pie does not get passed to the linker as it's not normally a thing that makes sense, unlike GCC which will unconditionally forward it on and potentially result in a linker error. However, LLD does support it, and manually forwarding it on works as desired, so do so to fully support FW_PIC with Clang and LLD.
