ATF version 2.2 and older does not disable SSP when
ENABLE_STACK_PROTECTOR is not set. This is because the compiler enables
SSP by default, and ATF does not pass -fno-stack-protector to the
compiler. Upstream commit 7af195e29a42 ("Disable stack protection
explicitly") fixed the issue for v2.3 and newer.
Add -fno-stack-protector in CFLAGS when
BR2_TARGET_ARM_TRUSTED_FIRMWARE_SSP is not set to fix older ATF
versions.
