> relative to the Buildroot tree, and thus may lead to unexpected results.
>
> For example, running this:
>     make -C buildroot O=my-O
>
> will not vreate my-O in the current working directory, but as a
> sub-directory of the Buildroot tree, here in buildroot/my-O
>
> Explain this in the manual (as is similarly done for BR2_EXTERNAL).
> Also add a note that $(O) will be created if missing.
