cxx_stdlib_overridden.tcl is a script that runs automatically when
MacPorts base is installed. It sets up some metadata in the registry.

The ports that rev-upgrade is newly finding to be broken are those that
have configure.cxx_stdlib set to libc++ but in fact link with libstdc++,
or vice versa. These need to be fixed by either making them link with
the selected stdlib (preferred), or changing configure.cxx_stdlib to
match what they are actually using.

Please open tickets or better yet PRs for affected ports.
