[build, doc] Obsolete Solaris 8 support

[build, doc] Obsolete Solaris 8 support

[Rainer Orth]

Continuing to support Solaris 8 is starting to cause lots of trouble:

* Regular support has ended in March 2009, and even extended support
  with special arrangements will end in March 2012.

* Access to Solaris 8 patches is restricted to customers with such
  arrangements, which I'm not.

* While I can test Solaris 8/SPARC in a Solaris 8 Branded Zone running
  on Solaris 10, this testing is limited since only the non-default
  alternate thread library is supported there.  I could test on bare
  metal if need be, but this will likely go away.

* Solaris 8/x86 testing is even worse: running it inside VirtualBox is
  dog slow and unreliable and Xen doesn't work at all.  I've finally
  been able to get myself a machine old enough to still run it or hack
  newer machines into running it, but I doubt all this trouble is worth
  it.

Therefore I'll soon commit this patch to obsolete Solaris 8 support in
4.7.  It will be removed in 4.8 then.

Tested by configuring with --with-target i386-pc-solaris2.8 and noting
the build fail in the gcc subdir, while it continues to work with
--enable-obsolete.

When obsoleting targets or other features, please update the release notes 
(gcc-4.7/changes.html).

Like this?  Or should I link to the UI threads removal patch, too?

I don't think such a link is needed.

Ok, I've checked in the patch.

Thanks.
