This brings the build-requirements up-to-date with us now requiring
a C++ host compiler. I optimistically increased the minimum required
GCC version listed from 2.95 to 3.4 as that is the earliest version
that could reasonably be called a C++98 compatible compiler (yeah,
lawrence will now argue that we want to require C++04 or how it was
called).
Installed. Suggestions for incremental improvements (including
actually verifying the requirements) welcome.
At least this fixes this P1 bug for me.
Thanks,
Richard.

* doc/install.texi (Tools/packages necessary for building GCC):
State ISO C++98 host compiler requirement. Increment minimum
GCC version required for building all languages for a cross-compiler
to 3.4 or later.
