I'm not really talking of build time detection, but rather referring to
the fact that we have Config.in options in Buildroot that tell us the
version of the kernel headers. So maybe glibc 2.24 should depend on
kernel headers >= 3.2.0. For now, we'll keep glibc 2.23, but then some
time later in the future, when 2.24 becomes the oldest supported glibc
version, glibc as a whole will be usable only for >= 3.2.0. Hopefully
by that time, all the people will have moved to newer kernels :)
