If one runs ./Configure -Duserelocatableinc ... everything is fine.
[Tests pass, install works, installed perl works]

If one re-runs ./Configure -Duserelocatableinc with the old config.sh in
place, Configure gets confused by the values it reads in. Notably
initialinstalllocation and installbin are now "I want relocating" type
paths starting "...", not absolute paths.

(don't be confused - the above is not from the system I'm using to run
perlbug)

I'm not (yet) sure what the correct fix is.

Is this fundamentally the same bug as subsequently reported by Andreas in #12055

The RT System itself - Status changed from 'new' to 'open'

No, it is not. That one is about runtime behavior, not configure-time behavior
