Since the main deprecation patches are now in, feel free to send further 
patches (to config.gcc and the release notes).

I can't quite figure out what the score people are up to, but it doesn't 
appear to involve a simultaneously maintained set of upstream components 
that are usable together in their current upstream forms; they got Linux 
kernel support upstream in 2009 (and don't seem to have maintained it much 
since then), some time after they got GCC support upstream (and then 
stopped maintaining it).

There may also be subtargets or target-specific features worth considering 
for deprecation (e.g. ARM -mwords-little-endian was mentioned in a 
previous cleanup discussion).
