Hello,

Currently svt-av1 FTBFS on x32 with the following errror:

As you can see, yasm is called with "-f elf" and not "-f elfx32"

That should be fixed upstream

I have forwarded the bugreport.
Just for the record though, it should be possible to override the
output format with

   set(CMAKE_ASM_NASM_OBJECT_FORMAT elfx32)
