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:
