It seems like you use a bogus toolchain and (or) cmake. Please try this:

mkdir build
cd build
${ANDROID_HOME}/cmake/3.6.4111459/bin/cmake \
-Wno-dev \
-DCMAKE_SYSTEM_NAME=Android \
-DANDROID_PLATFORM=android-21 \
-DANDROID_ABI=arm64-v8a \
-DANDROID_NDK=${ANDROID_NDK_ROOT} \
-DCMAKE_BUILD_TYPE=Release \
-DCMAKE_TOOLCHAIN_FILE=${ANDROID_NDK_ROOT}/build/cmake/android.toolchain.cmake \
-DCMAKE_ANDROID_NDK_TOOLCHAIN_VERSION=clang \
-DCMAKE_VERBOSE_MAKEFILE=ON \
-DENABLE_LIBCORKSCREW=OFF \
-DENABLE_LIBUNWIND=ON \
-DENABLE_LIBUNWINDSTACK=OFF \
-DENABLE_CXXABI=ON \
-DENABLE_STACKSCAN=ON \
-DENABLE_INPROCESS=ON \
-DENABLE_OUTOFPROCESS=ON \
..
cmake --build . --target ndcrash

ANDROID_HOME variable should point to Android SDK location.
