Continuing thoughts from the other ticket
(https://sourceware.org/bugzilla/show_bug.cgi?id=3D30127#c27).

Correct me if I'm wrong, but isn't the solib mapped before DT_AUDIT is read=
? So
the proposed la_premap wouldn't apply to the solib with the DT_AUDIT, only =
to
what it loads and whatever gets loaded later? Which doesn't sound at all li=
ke
what you want.
