It's the LD_ASSUME_KERNEL that fixes this, at least that was my experience.
Caveat - I haven't installed on Redhat 8 yet but I had this same problem on 7.2/7.3 (I forget which it was). Also I don't use the compat libs - you can do it without them if you have the glibc patch from Oracle. I think the end result is the same.
