If at all possible I would like elfutils to not turn into some
abstraction layer for broken non-GNU/Linux systems. I don't mind small
(mostly) obvious correct defines/checks or tweaks to help out people
using such broken systems. But if we need a lot more of these things I
think we should look if we can just import the necessary gnulib modules
to get portability functions.

Cheers,
