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 := false
ifneq ($(WITHOUT_HOST_CLANG),true)
# By default,host builds use clang for better warnings.
ART_HOST_CLANG := true
endif
修改后：
# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),false)
# By default,host builds use clang for better warnings.
ART_HOST_CLANG := true
endif
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
