I noticed that the target-specific sections in doc/install.texi need a little lover and care. It would be great could you have a look and streamline/update before the GCC 7 release.
Thanks! Also, I'm offering help around one particular aspect I noticed: References to dependencies on really, really old versions of binutils (talking 10+ years here) which I think we can remove. Let me follow-up with some of you with concrete suggestions around that. Gerald
