Compilation error #100

When running the vanilla build-ffmpeg.sh script I am always gettings this error:

``

--disable-asm fixes the problem.

Please retry after finding and deleting all gas-preprocessor.pl.

I got the same error.

After commenting out AS="gas-preprocessor..." in the build script (forcing AS="$CC"), the compiler gets a little bit further until it hits libavcodec/aarch64/simple_idct_neon.o with a bunch of "invalid operand" errors.

It did compile with the --disable-asm flag.

作者用的是这个项目的perl文件 https://github.com/libav/gas-preprocessor 一定要看清楚，github上有好多gas-preprocessor项目
