undefined reference to __stack_chk_guard happens when the code is built
with Stack Smashing Protection enabled, but that doesn't work well for
freestanding code (like bootloader/firmware code), unless it explicitly
provides the runtime code needed to support Stack Smashing Protection.
So indeed to override that, -fno-stack-protector needs to be passed
when building such bootloader/firmware code.
Best regards,
Thomas
