--- Comment #1 from Stan Cox <scox at redhat dot com> ---
Comments from Petr Machata who added ppc plt support to ltrace:
PPC PLT slots themselves are only used on first call, which means you never hit
them on prelinked binary or often don't hit them when attaching to a running
one.
ltrace goes to great lengths to simulate the as-if behavior, meaning as-if ppc
had sane PLT tables. It unprelinks stuff, singlestepping through the dynamic
linker.
