Jin Bo 903c5d58f0 configure: [loongson] adjust MMI check in configure After standardizing the use of 'pxor' in commit 'ebedd26', FFmpeg build failed with upstream compiler, for 'pxor' is not supported in time. This patch helps to workaround the build failure by checking whether 'pxor' is supported during configuration, if not, MMI will be disabled.

libavdevice provides an abstraction to access capture and playback devices.
libswresample implements audio mixing and resampling routines.
libswscale implements color conversion and scaling routines.

Tools

ffmpeg is a command line toolbox to manipulate, convert and stream multimedia content.
ffplay is a minimalistic multimedia player.
ffprobe is a simple analysis tool to inspect multimedia content.
Additional small tools such as aviocat, ismindex and qt-faststart.
