[PATCH] Default to an ARM cpu that exists

Regarding target/86383, it wasn't sufficient to not just pick arm6 for netbsd, as the default -mcpu is still arm6, which also fails to build. I assume the default is expected to be the oldest support, and I think now that's arm8, so maybe default to that. diff --git a/gcc/config.gcc b/gcc/config.
