From: Wu Zhangjin <wuzhangjin@xxxxxxxxx> As the "Fixups of Loongson2F" patch[1] to binutils have been applied into binutils 2.20.1. It's time to enable the options provided by the patch to compile the kernel. Without these fixups, the system will hang unexpectedly for the bug of processor. To learn more about these fixups, please refer to the following references.
