genkernel: tell user that shown kernel version is subject to change
When you start with fresh (unused) kernel sources, we will get Kernel
Version from KERNEL_DIR. If you already have compiled that KV, genkernel
maybe use your existing configuration from /etc/kernels (depends on other
settings like --mrproper).
Once your new kernel was built and you are saving configs (--save-config),
we will save the used configuration in /etc/kernels/kernel-config-${ARCH}-${KV}.
If you used --menuconfig during genkernel run to change kernel options like
CONFIG_LOCALVERSION or CONFIG_LOCALVERSION_AUTO or have modified kernel's
Makefile manually to change version, KV is subject to change once
genkernel has called 'make prepare'.
With this change we will tell user when KV has changed to end confusion like
shown in bug 521778.
