The question is why does...

  if (builtin_decl_implicit_p (BUILT_IN_ASAN_INIT))
    return;

in initialize_sanitizer_builtins() not emit a __asan_init while apparently...

tree fn = builtin_decl_implicit (BUILT_IN_ASAN_INIT);

in asan_finish_file() emits an apparenty unnecessary one in the wrong section.
