Description Paul Eggleton 2015-11-05 14:46:41 UTC
If OLDEST_KERNEL is set to a value newer than the kernel being built, unless the kernel has been appropriately patched you may end up with a glibc that doesn't work on the kernel being built. We should probably check OLDEST_KERNEL against the kernel being built and at least show a warning if it's older.

I've ended up implementing this so I might as well take it back.
