1.1.6的u-boot老掉牙了，用版本高的編譯器編譯會出現莫名其妙的問題（實際是我不懂

makefile:263: recipe for target 'u-boot' failed
這個是錯誤log
什麼eabi版本高了，網上查，什麼浮點啊，改cpu配置的都不起作用，本來打算換低版本的編譯器了，算了，突然看到說加上引數 -nostdlib
於是用make -nostdlib 編譯通過，
網上查到的
問題解決：arm-none-linux-gnueabi-gcc加上-nostdlib選項即可
機理-nostdlib
不連線系統標準啟動檔案和標準庫檔案，只把指定的檔案傳遞給聯結器。
這個選項常用於編譯核心、bootloader等程式，它們不需要啟動檔案、標準庫檔案。
