TODO: do we need this to be done for vDSO as well?
- Do not check pointer signature before we are relocated
  as this might be a pointer to global.
- Sign function pointers returned from __vdsosym.
- Do not apply PAC relocs in __dls2, because we may need
  to do this second time in __dls3. We can't do this as
  we overwrite authentication scheme when applying relocs.
