Yes, s390 should select that :)

But, is there any switch or option I need to set when compiling clang,
so it knows about the kcfi sanitizer?

I get:
clang-16: error: unsupported option '-fsanitize=kcfi' for target 's390x-ibm-linux'

clang version 16.0.0 (https://github.com/llvm/llvm-project.git e02110e2ab4dd71b276e887483f0e6e286d243ed)
