+ This makes the assumption that all .opd entries are always relocated
+ by the same offset the section itself was relocated. This should
+ always be the case for GNU/Linux executables and shared libraries.
+ Note that other kind of object files (e.g. those added via
+ add-symbol-files) will currently never end up here anyway, as this
+ function accesses *target* sections only; only the main exec and
+ shared libraries are ever added to the target. */
