Let me reply to libc-alpha so that it has a chance to be seen.

The problem I see with your patch, is that there seems to be no
fallback for the case where you compile this with kernel headers that
define KERN_NGROUPS_MAX but do run it on an older kernel.  Check how
we do this with kernel-features.h,
