交叉编译ffmpeg失败、提示好像是工具链问题，求解答
aarch64-histbv100-linux-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.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.
