I've come across more than one file format that _hashes_ the build
path and then uses that value as a debug/interface/build identifier.
Crucially, as the build path is hashed, it does not appear as a
literal string in the binary, so not seeing the build path in
diffoscope is not conclusive.

Whilst I've seen this used as part of the Link-Time Optimisation
puzzle, the switch to disable stuff like that might be in the linker
or debug area of your compiler docs — not the optimisation part.

That would be my guess anyway... Am throwing it over the wall given
you seem to be working on this as we type. :)  No doubt someone much
more informed about this file format will chime in and correct me.


Best wishes,
