scripts/cc-can-link.sh tests if the compiler can link userspace programs. When $(CC) is GCC, it is checked against the target architecture because the toolchain prefix is specified as a part of $(CC). When $(CC) is Clang, it is checked against the host architecture because --target option is missing. Pass $(CLANG_FLAGS) to scripts/cc-can-link.sh to evaluate the link capability for the target architecture.
