Have you tried to run any libc5-program lately? Or a.out binaries?
If there's an issue with libc5, then please report a bug; anything ELF is
supposed to continue running.
Support for a.out was removed indeed, I forgot about that. It boils down
to maintenance really: no one was interested in becoming a maintainer and
I reckon calls to fix bugs were unanswered for years. Someone *has* to do
the work, things do not happen automagically.
