Well, you have it: hwloc_proc_getmembind()
How it'd be called by the OS in the future is unknown of course.

It's always system call or glibc function, it depends on the system and
we can't know where it'd be implemented in the future. Or our lack of knowledge of
which system call can provide the functionality.

We'd have to handle a big list of combinations of parameters in that
case. I'd rather add a paragraph to the documentation that just
explains that not everything is available on all OSes, or hwloc just
doesn't know that it got implemented.
