But we are not supposed to talk about GNU there, so I think it's not
helpful for describing GNU features.
If I'm wrong about that and we can document glibc specifics there (such
as DF_GNU_1_UNIQUE), then I guess that's fine, except that you will be
hard-pressed to find a glibc target that implements dynamic linking, but
not these ELF extensions (because they will be in generic code). So the
processor-independent GNU/Linux ABI isn't really the right place.
These features are also not likely to be implemented by musl, ucLibc,
LLVM libc, even on Linux, because they *are* GNU features, not Linux
platform features.
Thanks,
Florian
