ubuntu16.04 64bit编译android5.1错误

之前使用ubuntu12.04 64bit编译android时并没有出现较大的错误，将平台更换到16.04时编译出错，且该错误并不好查找，因此特意记录下来。

source_android代表你的android源码根目录

1.修改

cd  <source_android>/art/build/vim Android.common_build.mk    //修改第119行修改前：# Host.ART_HOST_CLANG := falseifneq ($(WITHOUT_HOST_CLANG),true)# By default, host builds use clang for better warnings.ART_HOST_CLANG := trueendif修改后：# Host.ART_HOST_CLANG := falseifneq ($(WITHOUT_HOST_CLANG),false)# By default, host builds use clang for better warnings.ART_HOST_CLANG := trueendif

2.修改
经过第一次修改之后发现编译还是报同样的错误，执行下面：

 cp /usr/bin/ld.gold   <source_android>/prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.6/x86_64-linux/bin/ld 

3.修改过上述代码后，最好执行一次make update-api，在make
