    glibc: Avoid multilibbing on wordsize.h
    
    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/.
