That sounds like something going wrong with the configure invocation - 
have a look in ffbuild/config.log around the area of testing the assembler 

If you're erroring out at this spot, the cherrypicks I mentioned won't 
probably help, but I can help with whatever other issues you run into 
regarding this.

I haven't tested building ffmpeg with the cross toolchain myself though, 
but in general, gas-preprocessor should be migrated into a thing of the 
past now.

It's not harmful in itself no, but it's something that shouldn't really be 
needed any longer, so any steps to activate it feels like a step in the 
wrong direction to me (even if the right direction requires more 
debugging). If it's temporary I don't want to block anything though.
