Bug#830886: ffmpeg FTBFS for mips64el on configure

Package: ffmpeg

Package ffmpeg FTBFS for mips64el on configure with the following error:
> ERROR: LoadLibrary/dlopen not found for avisynth

Error message from config.log:
> /usr/bin/ld: /tmp/ffconf.09oJ6qCG.o: linking -mnan=2008 module with previous -mnan=legacy modules
> /usr/bin/ld: failed to merge target specific data of file /tmp/ffconf.09oJ6qCG.o
> collect2: error: ld returned 1 exit status

The reason for that is usage of -mips64r6 flag that triggers -mnan=200 flag.

Solution is to disable mips64r6 in debian rules.
Patch that includes this fix is attached.

I will rebuild locally latest ffmpeg version (7:3.1.1-1) for mips/mipsel/mips64el to confirm that patch fixes mips64el and does not break mips/mipsel.

Regards,
Dejan
