Commit glibc-2.14~10 disallowed rtld self loading to avoid a segfault that used to happen when rtld was loading itself in normal mode. Unfortunately, that commit disallowed all modes of self loading, including those that used to work before. This change limits the check for self loading to normal mode only, so that instruments like ldd could handle rtld properly.
