If OLDEST_KERNEL is set to a value that's too new then the failure you
get is anything but subtle: glibc will just print "kernel too old" and
exit.  I guess we could enhance that message to refer directly to
OLDEST_KERNEL to make it a bit more obvious what you need to do.  Also,
we could teach kernel.bbclass to issue a diagnostic if you try to build
a kernel that's older than OLDEST_KERNEL.
