再详细说一下注释中没有的可能有疑问的地方：

# 要链接的静态库
#LDLIBS         += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libc.a
#LDLIBS         += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libg.a
#LDLIBS         += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libm.a
#LDLIBS      += /Users/ch-yanghl/gcc-arm-none-eabi/lib/gcc/arm-none-eabi/5.4.1/libgcc.a
#LDLIBS      += /Users/ch-yanghl/gcc-arm-none-eabi/arm-none-eabi/lib/thumb/libnosys.a

-这一块为什么要注释：因为文中使用了

# 设置ld链接脚本文件
LDSCRIPT    := $(SCRIPT_DIR)/stm32_flash.ld

/*stm32_flash.ld文件中最后部分内容*/
/DISCARD/ :
  {
    libc.a ( * )
    libm.a ( * )
    libg.a ( * )
    libgcc.a ( * )
  }

这个ld脚本文件，该文件中已经包含了这些库。
