The linker script CONSTRUCTORS keyword is only meaningful "when linking object file formats which do not support arbitrary sections, such as ECOFF and XCOFF"[1] and is ignored for other object file formats. LLVM's lld does not yet accept (and ignore) CONSTRUCTORS, so just remove CONSTRUCTORS from the linker scripts as it has no effect.
