This does not match what all the other major linkers do (LLD, gold). It also
isn't properly documented anywhere that I could find. Additionally, why would
someone generate a PIE just for it to be loaded *always* at the same specified
address? What is the use case?

>From what I know, if a PIE has a specific non-0 load address, it should be
taken as a hint or preferred load address, but then the program loader should
be able to apply any slide to it as it sees fit.
