android - ffmpeg 构建错误看起来 tmp 文件创建失败？

Question

 ./configure --target-os=android --prefix=$PREFIX \
  --enable-cross-compile --enable-runtime-cpudetect --disable-asm --arch=arm \
  --cc=$PREBUILT/linux-x86_64/bin/arm-linux-androideabi-gcc \
  --cross-prefix=$PREBUILT/linux-x86_64/bin/arm-linux-androideabi- \
  --disable-stripping --nm=$PREBUILT/linux-x86_64/bin/arm-linux-androideabi-nm --sysroot=$PLATFORM --enable-gpl --enable-shared --disable-static --enable-small  --disable-ffprobe --disable-ffplay --disable-ffmpeg --disable-ffserver --disable-debug --extra-cflags="-fPIC -DANDROID -D__thumb__ -mthumb -Wfatal-errors -Wno-deprecated -mfloat-abi=softfp -marm -march=armv7-a"

这是输出日志:

Makefile:2: config.mak: 没有那个文件或目录
Makefile:67: /common.mak: 没有那个文件或目录
Makefile:109: /libavutil/Makefile: 没有那个文件或目录
Makefile:109: /library.mak: 没有那个文件或目录

/opt/android/android-sdk-linux/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc is unable to create an executable file.
C compiler test failed.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.freenode.net.
Include the log file "config.log" produced by configure as this will help
solve the problem.

但我的 gcc 路径工作正常

/opt/android/android-sdk-linux/ndk-bundle/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-gcc
arm-linux-androideabi-gcc: fatal error :没有输入文件编译终止。

我好像没有创建临时文件，我在/tmp 中找不到临时文件

这是 config.log 文件的结尾:

默认的 NDK 工具链不适合编译 Autoconf 项目。您需要按照 here 所述生成独立工具链.如果这没有帮助，您应该检查 config.log 中的失败命令，看看到底出了什么问题(简单的 gcc 测试无济于事，因为错误可能是由链接器引起的)。
