Okay, I did this and I see this:

$ grep _ASH busybox.cfg.suid busybox.cfg.nosuid

I still don't understand. Your procedure generated which you say are
problematic, I do not understand IN WHAT WAY they are problematic?
HOW are you using these files?

Let me try harder:
I never used busybox.cfg.[no]suid files myself.
Also, I am not good at reading minds. You need to walk me through the ENTIRE
procedure which ends with a problem.

You are on the CC list for the bug.
