We cannot rely on the clang compiler to generate the trampoline entry
and the right mangling because `__attribute__((naked))` does not
prevent clang from generating TSAN function entry stub
(`__tsan_func_entry`). Even with `__attribute__((no_sanitize_thread)`
annotation clang generates the entry stub.
