[PATCH] toplevel: Error out if using --disable-libstdcxx with bootstrap [PR105474]

[Andrew Pinski]

Bootstrapping and using --disable-libstdcxx will cause a build failure deep in 
compiling
stage2 so instead error out early in the toplevel configure so it is more user 
friendly.

Bootstrapped and tested on x86_64-linux-gnu.
Also made sure --disable-libstdcxx without --disable-bootstrap failed.

        PR bootstrap/105474

ChangeLog:

        * configure: Regenerate.
        * configure.ac: Error out if libstdc++ is not enabled
        with bootstrapping.
