Subject: stack-protector: fix CC_HAS_STACKPROTECTOR_NONE depend on -fno-stack-protector

commit（2a61f4747eeaa85ce26ca9fbd81421b15facd018）rename CC_STACKPROTECTOR_NONE
config. but unfortunately if the compiler support option -fno-stack-protector, 
CC_HAS_STACKPROTECTOR_NONE will not be disabled.

CC_HAS_STACKPROTECTOR_NONE and CC_STACKPROTECTOR_STRONG will be enabled at once,
as the following conditions:
        1. gcc support -fno-stack-protector & -fstack-protector-strong
        2. enabled CC_STACKPROTECTOR_STRONG & STACKPROTECTOR
        3. disabled CC_HAS_STACKPROTECTOR_NONE
