Some projects are still built with our host GCC 4.8, which doesn't support -fstack-protector-strong. The combo .mk files are used by GCC and clang, so it's not safe to turn on -fstack-protector-strong there. Instead, do it in the clang-specific .mk for now. We can clean this up when elfutils (the last code built for the host with GCC that I'm aware of) is built by clang. We'll be able to remove the host GCC prebuilts too!
