当我在ubuntu16.04上构建android5.0时，我收到以下错误：

为什么会出现？

我通过修改$ANDROID_REPO/art/build/Android.common_build.mk：

解决了这个问题

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

确保ART_HOST_CLANG = true。然后，我创建了以下符号链接：

ln -sf /usr/bin/ld.gold $ANDROID_REPO/prebuilts/gcc/linux-x86/host/(glibc version)/x86_64-linux/bin/ld
