build/core/host_shared_library_internal.mk:51: recipe for target ‘out/host/linux-x86/obj/lib/libart.so’ failed 1

解决方法:
clang编辑器的问题，在art/build/Android.common_build.mk 中将host 默认编辑器使用clang关掉，找到WITHOUT_HOST_CLANG

关闭clang：

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

实测有用
