Target deprecation, round two

[Zack Weinberg <zack at codesourcery dot com>]

Apologies for not getting back to this for so long.

This is my updated list of targets to be deprecated in 3.3 and removed
in 3.4.  It's exhaustive - if there's something currently listed in
mainline config.gcc as deprecated but not on that list, it's been
reprieved.

Relative to the previous posting, I took off all of the targets in
which anyone expressed even the slightest interest; this is consistent
with what we did last time round, but I'm not promising to keep doing
that.

It is not clear to me whether interest remains in *-*-linux*libc1*.
I'm leaving it on the deprecation list for now.
