[PATCH, wwwdocs] gcc-11/changes: C++11 is now required to build GCC

[David Malcolm]

This summarizes GCC 11's change in build requirements from C++98 to
C++11, for the release notes.  I've put it in the Caveats immediately
below the "The default mode for C++ is..." change hence the wording.

I've based it on the change to gcc/doc/install.texi in the
GCC source tree, which was 5329b59a2e13dabbe2038af0fe2e3cf5fc7f98ed
there.

Validates.

OK to commit?
