The sh decompressor code triggers stack-protector code generation when using CONFIG_CC_STACKPROTECTOR_STRONG. As done for arm and mips, add a simple static stack-protector canary. As this wasn't protected before, the risk of using a weak canary is minimized. Once the kernel is actually up, a better canary is chosen.
