You need to have a BSP definition file, which tells the kernel meta
data and configuration phases how to actually configure the board from
the collection of fragments.

That error is telling you that you don't have a BSP definition file
that can be located by the tools.

If you want to have your own machine name, but otherwise re-use the
qemux86 configuration, you can put: KMACHINE_armour-whiplash =
"qemux86", and the tools will use that as the starting point for
configuration.

If you need to define your own BSP definition file, search for the
recent thread with this subject: "[yocto] Kernel patches pulled from
BSP definition file are not applied", and you'll see an example of how
to define one in your own layer.
