 * dladdr(3) is not POSIX but a GNU extension, and is not available on AIX.
 *
 * We only support Dl_info.dli_fname here as this is the only thing that is
 * used of it by libjli.so. A more comprehensive port of dladdr can be found
 * in the hotspot implementation which is not available at this place, though.
