make: *** [out/host/linux-x86/obj32/lib/libart.so] Error 1


reason：ubuntu16.04 clang problem

1.Off clang，gedit file art/build/Android.common_build.mk ,find out WITHOUT_HOST_CLANG
diff：
# Host.
ART_HOST_CLANG := false
ifneq ($(WITHOUT_HOST_CLANG),true)
# By default, host builds use clang for better warnings.
- ART_HOST_CLANG := true+ ART_HOST_CLANG := false
endif

2. rebuild env
sudo apt install git-core gnupg flex bison gperf build-essentialzip \
curl zlib1g-dev gcc-multilib g++-multilib libc6-dev-i386lib32ncurses5-dev \
x11proto-core-dev libx11-dev lib32z-dev ccache libgl1-mesa-dev \
libxml2-utils xsltproc unzip m4  && sudo apt-get update

No need to make clean, continue make again .
