Also tweak the kernel's Makefile to use -nostdinc and -nostdinc++. This prevents us from picking up random headers from ../Root, which may include older versions of kernel headers. Since we still need <initializer_list> for Vector, we specifically include the necessary GCC path. This is a bit hackish but it works for now.
