Cross-compile Loongson MIPS64 version of ffmpeg（交叉编译失败，后续再研究）

交叉编译失败，ffmpeg的configure中没有cc参数，以下操作依然调用x86编译器，后续再研究交叉编译

Compilation environment description

System: deepin V20
Platform: x86_64
Cross Compiler:mips-loongson-gcc7.3-linux-gnu

Cross compilation environment construction

This compilation uses gcc7.3, to build a cross-compilation environment, please refer to Building a Loongson MIPS64 cross-compilation environment on the x86_64 platform
