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.
