Once another header #includes <bits/wordsize.h>, there is a
potential recursion going on because the
multilib_header_wrapper.h #includes <bits/wordsize.h> again!

This should not happen because an __arm__ (32-bits) or an
__aarch64__ (64-bits) environment guarantees that we will
be getting the correct definition, but when building against
a different target (like BPF), recursion is what happens.

This can be seen, for instance, when building eBPF programs
from the kernel with `clang -target bpf', such as the ones
located in linux/tools/testing/selftests/bpf/.
