这是一个基于Ubuntu和GCC的操作系统编译Makefile
可以用来生成二进制程序和APP，以及Image镜像文件。
详细的Makefile内容如下：
ifndef GCCPREFIX
GCCPREFIX :=
endif
ifndef ARCH
ARCH := x86
endif
ifndef DEBUG
DEBUG := 1
endif
TARGET := target
AS := nasm
CC := $(GCCPREFIX)gcc
LD := $(GCCPREFIX)ld
OBJCOPY := $(GCCPREFIX)objcopy
ifeq ($(ARCH), x86_64)
QEMU := qemu-system-i386
CFLAGS += -Wall -Wno-format -Wno-unused -fno-pic
CFLAGS += -gstabs -std=gnu99 -static -m64 -fno-stack-protector
CFLAGS += -I ./sys/include -I ./libc/include
CFLAGS += -ffunction-sections -nostdlib -nostdinc -fno-builtin -ffreestanding
QEMU_FLAGS += -no-reboot -d in_asm -m size=128
else
QEMU := qemu-system-i386
CFLAGS += -Wall -Wno-format -Wno-unused -fno-pic
CFLAGS += -gstabs -std=gnu99 -static -m32 -fno-stack-protector
