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