Fabrice Fontaine 7b18f26d82 s390: disable SSP when needed
[ Upstream commit 42e8d652438f5ddf04e5dac299cb5e623d113dc0 ]

Though -nostdlib is passed in PURGATORY_LDFLAGS and -ffreestanding in
KBUILD_CFLAGS_DECOMPRESSOR, -fno-stack-protector must also be passed to
avoid linking errors related to undefined references to
'__stack_chk_guard' and '__stack_chk_fail' if toolchain enforces
-fstack-protector.
