[U-Boot-Users] [PATCH] Conditionally add -fno-stack-protector to CFLAGS

When compile-testing on powerpc, I get errors like this:

/home/hskinnemoen/work/git/u-boot/net/nfs.c:422: undefined reference to `__stack_chk_fail_local'

This seems to be because -fstack-protector is on by default, so
explicitly disable it on all architectures that support the option.
