This looks good to me, though I've Cc'd Kees as apparently the original
author from commit 8779657d29c0 ("stackprotector: Introduce
CONFIG_CC_STACKPROTECTOR_STRONG") in case there was a particular reason
this wasn't done in the first place.

(Happy to apply with acks from Kees and ARM, SH maintainers if nobody
else does).
Cheers
James
