ldso: fix fdpic builds
Commit 33cb7f0b4 tried to add a small optimization for skipping unnecessary
.dynamic adjustments, but did so by referencing an opaque type. While this
works for non-fdpic targets (since the type can be cast to an integer), it
falls apart for fdpic targets where the type is actually a structure.
Since FDPIC can't support this optimization without walking a series of
linked structures, just skip it.
