you have to post the actual error message also, you should post a config.log from the build directory chances are you need to just re-run `gcc-config`

Also, it's just not diffutils, I get the same error while compiling alsa-libs as well.
Created attachment 47048 [details] Diffutils config.log
I ran gcc-config -O and I still can not compile anything.
