Subject: stackprotector: Unify the HAVE_CC_STACKPROTECTOR logic between
 architectures

Instead of duplicating the CC_STACKPROTECTOR Kconfig and
Makefile logic in each architecture, switch to using
HAVE_CC_STACKPROTECTOR and keep everything in one place. This
retains the x86-specific bug verification scripts.
