Note that elf.h is somewhat special. We import it as-is from glibc and
like to not have divergence if at all possible. So could you try
submitting to glibc upstream first? (libc-alpha@sourceware.org)
They might say they expect your features.h to provide these macros.
But they might also just take the change as is. If not we'll figure
something out for elfutils.

Thanks,
