[Buildroot] [PATCH 1/1] boot/at91dataflashboot: disable stack-protector

[Fabrice Fontaine]

Disable stack-protector to avoid the following build failure:

/home/buildroot/autobuild/instance-1/output-1/host/bin/arm-buildroot-linux-gnueabi-ld -T elf32-littlearm.lds -Ttext 0 -n -o DataflashBoot-1.05.out objs/cstartup_ram.o objs/at45.o objs/com.o objs/dataflash.o objs/div0.o objs/init.o objs/main.o objs/stdio.o objs/asm_isr.o objs/jump.o objs/_udivsi3.o objs/_umodsi3.o objs/led.o
/home/buildroot/autobuild/instance-1/output-1/host/bin/arm-buildroot-linux-gnueabi-ld: objs/main.o: in function `main':
main.c:(.text.startup+0x834): undefined reference to `__stack_chk_guard'

Fixes:
