OLDEST_KERNEL is used in glibc recipe only; it would be much better
to build SDK's glibc with an --enable-kernel matching the target
distribution. E.g. by setting a special 'OLDEST_KERNEL_nativesdk'
variable.
glibc included with master has a minimum kernel version due to various ABIs that
it uses. My understanding is that the OLDEST_KERNEL does indeed match for the
nativesdk.

This check should be made overridable for environments which do not
build SDKs.
Using the buildtools-tarball will result in these issues.. (that is a lot more
common, at least for us due to the wide variety of distributions that don't have
minimum tool versions...)

This check does not work when you build e.g. in an LXC container. You
could define something like
| SDK_UNAME ??= "${@' '.join(os.uname())}"
and do the checks on this.
