ubuntu16.04 64bit編譯android5.1錯誤

之前使用ubuntu12.04 64bit編譯Android時並沒有出現較大的錯誤，將平臺更換到16.04時編譯出錯，且該錯誤並不好查找，因此特意記錄下來。

source_android代表你的android源碼根目錄

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

2.修改
經過第一次修改之後發現編譯還是報同樣的錯誤，執行下面：

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.修改過上述代碼後，最好執行一次make update-api，在make
