This change fixes two warnings from _dl_lookup_address. The first warning comes from dropping the volatile keyword from desc in the call to _dl_read_access_allowed. We now have a full atomic barrier between loading desc[0] and the access check, so desc no longer needs to be declared as volatile. The second warning comes from the implicit declaration of _dl_fix_reloc_arg. This is fixed by including dl-runtime.h and declaring _dl_fix_reloc_arg in dl-runtime.h.
