android armv7编译问题

[Guanmoyu]

NDK版本：android-ndk-r20
compile.sh中build_android_fn ()如下：

build_android_fn ()
{
    echo "android armv7-a"
    mkdir -p build-android-armv7
    pushd build-android-armv7
    cmake -DCMAKE_TOOLCHAIN_FILE=$ANDROID_NDK/build/cmake/android.toolchain.cmake \
          -DANDROID_ABI="armeabi-v7a" \
          -DANDROID_ARM_NEON=ON \
          -DANDROID_PLATFORM=android-24 \
          -DNCNN_OPENMP=OFF \
          -DNCNN_REQUANT=ON \
          -DNCNN_BENCHMARK=OFF \
          -DNCNN_IM2COL_SGEMM=ON \
          -DANDROID_STL=c++_static \
          ..   
    make -j3
    make install
    popd
}

编译过程中错误信息如下：
