libgcc for boot environment isn't always present and compatible. libgcc is often absent if endianness or bit-size at boot is different from running OS. libgcc may use optimised opcodes that aren't available on boot time. So instead of relying on libgcc shipped with the compiler, supply the functions in GRUB directly. Tests are present to ensure that those replacement functions behave the way compiler expects them to.
