![]() I got some undefined references to __stack_chk_fail in arch/powerpc/boot/stdio.o and arch/powerpc/boot/prom.o when I was trying to build a kernel on Ubuntu Edgy Eft - which includes Stack Smashing Protection. This patch adds -fno-stack-protector to BOOTCFLAGS in arch/powerpc/boot/Makefile (why does BOOTCFLAGS depend on HOSTCFLAGS and not CFLAGS?).
