ldso: process RELR only for non-FDPIC archs
the way RELR is applied is not a meaningful operation for FDPIC (there is no single "base" address). it seems unlikely RELR would ever be added for FDPIC, but if it ever is, the behavior and possibly data format will need to be different, so guard against calling the non-FDPIC code.
