Applied to master, thanks.

Following this, we should drop gcc 7.x support. However, one defconfig
(roseapplepi) still uses gcc 7.x. I've notified Peter Korsgaard on IRC,
and I am doing it here as well: if this defconfig is not updated to a
newer kernel that builds with gcc >= 8.x, we will have to drop support
for this defconfig.
