编译FFmpeg报错C编译器测试失败

/home/edward/bin/ndk/android-ndk-r14b/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86_64/bin/arm-linux-androideabi-clang 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 "ffbuild/config.log" produced by configure as this will help
solve the problem.

这个报错的原因是NDK没有配置好，选择合适的NDK版本;
如果调整NDK版本仍未解决，可以尝试下载ffmpeg release出来的各种稳定版本
目前4.0.3和3.4.5使用ndk/android-ndk-r14b完全没有问题
移植ffmepg可以参考CSDN上的这篇文章
