Masahiro Yamada June 14, 2018, 10:36 a.m. UTC 
HAVE_CC_STACKPROTECTOR should be selected by architectures with
stack canary implementation.  It is not about the compiler support.

For the consistency with commit 050e9baa9dc9 ("Kbuild: rename
CC_STACKPROTECTOR[_STRONG] config variables"), remove 'CC_'
from the config symbol.

I moved the 'select' lines to keep the alphabetical sorting.
