关于编译x264时出现的for Cortex-A8 erratum because it has no mapping symbols问题

linux下编译x264库时提示警告信息：cannot scan executable section 1 of libx264.a(dct-a.o) for Cortex-A8 erratum because it has no mapping symbols

要去掉该警告信息，将Makefile中含有 (STRIP) -x 的地方语句

-@ $(if $(STRIP), $(STRIP) -x $@) #delete local/anonymous symbols, so they don't show up in oprofile, except the mapping symbols

替换为

-@ $(if $(STRIP), $(STRIP) -x -K \$$a -K \$$t -K \$$d $@) #delete local/anonymous symbols, so they don't show up in oprofile, except the mapping symbols

即可。

注：红色部分是增加的内容，Makefile中总共有2处需要修改。
