What's avr-libc to do with it?
-mint8 has never been a multilib option and I don't know if avr-libc was 
supposed to build with -mint8 in the past.

Note that the option is broken in 4.5 and 4.6 already, so the option would have
to be removed in stage 3/4 of the compiler that is intended for
bugs/documentation updates only. It's up to the maintainers, of course.

If the patches above it all that needs to be done, it's maybe not that hard to
get it to work again, and mybe it's even possible without frontend changes.
