reproduce:
        wget https://git.kernel.org/cgit/linux/kernel/git/wfg/lkp-tests.git/plain/sbin/make.cross -O ~/bin/make.cross
        chmod +x ~/bin/make.cross
        git checkout 2d81d425b6d5cc2262912cce9f9ec7f706a3ea65
        # save the attached .config to linux build tree

Note: the arm-platforms/irq/irqchip-4.8 HEAD 3faf24ea894a34887c0ca412f1643540251b9d82 builds fine.
