From 6c3b05b74ccd49d8ba246bfef0c2e549b9f2bf7b Mon Sep 17 00:00:00 2001 From: Fabrice Fontaine Date: Tue, 29 Oct 2019 16:14:18 +0100 Subject: [PATCH] Makefile: unconditionally disable SSP Though -nostdlib is passed in $(CFLAGS), -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.
