I'm confused.  Is the glibc build process testing for features on the
_currently running kernel_ in some fashion, or is it testing for
features in headers provided by the kernel-headers package (which is a
proper BR already)?  I would expect the latter, meaning the currently
running kernel doesn't really matter.
