I think doing it manually with gdb should be fairly straightforward.
Something like
gdb /bin/true
and then in gdb you just do
b main
run
and then
catch syscall group:process
c
and it should stop at the exit_group or exit system call.
At that point you can just do
info registers
and see if they match what user space *should* be. They'll probably be
complete garbage without the fix.
I do not have an alpha or m68k machine to test (and not the
energy/inclination to set up some virtual environment in qemu either).
But it should be easy if you already have that environment.
