That's inaccurate. All it takes it defining ELF_PLATFORM in the kernel.
On the glibc side, using important hwcaps or known platform strings are
both supported, whatever your machine wants to do. I'm sure that what I
told you to do from the very start was "AT_HWCAP and/or AT_PLATFORM,
whatever the kernel community for your architecture decides."
Thanks,
