We have not used this mechanism when we added support for additional
registers to be passed to the PLT callbacks. Looking at commits
14c5cbabc2d11004ab223ae5eae761ddf83ef99e and
5cdd1989d1d2f135d02e66250f37ba8e767f9772, there is no way for an audit
module to notice if these additional fields are maintained by glibc.
