Oh, very much so: someone installed a version of GCC they compiled by
hand, and the support library for that was loaded in preference to the
system library.

Sadly, when the system was updated this broke thoroughly.

Reinstall.  Your system is probably thoroughly broken.

You likely need to remove the hand-installed GCC and support libraries
as part of this.  It /might/ come back to life if you do that, or it
might not.

Sorry.  In future I advice y'all to have a good backup to roll back a
failed upgrade like this.
