• Subject: [build, doc] Obsolete Solaris 8 support

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.
