This should be able to reside in arch/arm/mach-socfpga/config.mk and so
it should be moved there. It might need to be done under "archprepare".
That would also let us gate even trying it with an ifeq, like we do
currently. I also don't see that you tested this "make O=/tmp/somedir"
(which is not the HANDOFF_PATH thing) and I expect it doesn't work there
as it references ".config" and not "$(objdir)/.config".

Finally, since you mentioned AIs in other emails, we do not yet have a
formal policy for or against their usage in this project (it is
something we need to discuss) but at a minimum the Fedora policy makes
sense to me if using one:
