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.

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...)
