Follow-up Comment #1, bug #50715 (project grub):
Well, this code is run as the very first thing, before any memory allocator is
active. I guess we could use different, more "safe" stack location until
memory size is detected. But that also means we must restrict max image size,
so we still need to have some safe limit statically. In which case we can
simply move stack lower.
