Thanks for checking!

I don't really know how inline works across different gcc versions or
across distro versions. I see that various distributions patch elfutils
to contain something like:

#if defined(__GNUC_GNU_INLINE__) || defined(__GNUC_STDC_INLINE__)
#define inline inline __attribute__ ((gnu_inline))
#endif

Maybe that can be pushed upstream if it is the correct behavior that is
needed by elfutils.
