This bit?

define rule_vmlinux__
set -e
$(if $(filter .tmp_kallsyms%,$^),,
echo ' Generating build number'
. $(src)/scripts/mkversion > .tmp_version
mv -f .tmp_version .version
$(Q)$(MAKE) $(build)=init
)
$(call cmd,vmlinux__)
echo 'cmd_$@ := $(cmd_vmlinux__)' > $(@D)/.$(@F).cmd
endef
Is it possible to define $(SINGLE_MAKE) or something as well as $(MAKE),
where it strips the -j, and use that in the instances where it can't
take a -j? Would be nice to get rid of that one last warning ... ;-)
