When C++ support is enabled, configure unconditionally probes `-lstdc++` and keeps it in LIBS if the link test succeeds. On platforms using libc++, this probe can succeed at compile time (if libstdc++ headers/libraries happen to be installed) but then cause runtime failures when configure tries to execute test binaries because `libstdc++.so.6` isn't actually available. Add a `--with-cxx-stdlib=<libstdc++|libcxx>` option that lets the build system specify which C++ standard library to link. When given, the probe is skipped and the specified library is linked directly. When not given, the original probe behavior is preserved.
