chmod +x ~/bin/make.cross
# save the attached .config to linux build tree
make.cross ARCH=arm
Note: the linux-review/fu-wei-linaro-org/acpi-clocksource-add-GTDT-driver-and-GTDT-support-in-arm_arch_timer/20161116-004444 HEAD 47004b0566d2fd65c05836078319b02c5af2a1fc builds fine.
It only hurts bisectibility.
