| 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. |
| |
| Fixes: |
