[PATCH 1/3] kcsan: Don't expect 64 bits atomic builtins from 32 bits architectures

Activating KCSAN on a 32 bits architecture leads to the following link-time failure: LD .tmp_vmlinux.kallsyms1 powerpc64-linux-ld: kernel/kcsan/core.o: in function `__tsan_atomic64_load': kernel/kcsan/core.c:1273: undefined reference to `__atomic_load_8' powerpc64-linux-ld: kernel/k
