<br>
This should not happen because an __arm__ (32-bits) or an<br>
__aarch64__ (64-bits) environment guarantees that we will<br>
be getting the correct definition, but when building against<br>
a different target (like BPF), recursion is what happens.<br>
<br>
This can be seen, for instance, when building eBPF programs<br>
from the kernel with `clang -target bpf', such as the ones<br>
located in linux/tools/testing/selftests/bpf/.<br>
