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. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
