修改 build/core/clang/HOST_x86_common.mk

解决方法（二）
修改 art/build/Android.common_build.mk
# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),true)
# By default, host builds use clang for better warnings.
ART_HOST_CLANG := true
endif改为
# Host.
ART_HOST_CLANG := false
ifeq ($(WITHOUT_HOST_CLANG),false)
# By default, host builds use clang for better warnings.
ART_HOST_CLANG := true
endif仍然不起作用
解决方法（三）
cp /usr/bin/ld.gold prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.11-4.8/x86_64-linux/bin/ld这个之后，编译通过。

1、将prebuilts/gcc/linux-x86/host/x86_64-linux-glibc2.15-4.8/x86_64-linux/bin/ld 备份
