Hi,

Latest yocto still take "CentOS 7.x" as Supported Linux Distributions. 
But centos7 have kernel version 3.10.

But we have some archs, like aarch64, set OLDEST_KERNEL to 3.14. Without 
"-r ${OLDEST_KERNEL}",

some recipes which will run qemu during configure or compile will failed 
with error:

FATAL: kernel too old

How about add it back?


Thanks

Changqing
