How curious ... Why doesn't prelinking work when you use the TLS-enabled
link loader?  Does this mean that any TLS-enabled application, even when
prelinked, isn't going to benefit anyway?

The reason you need to use that link loader is because the default i386
one doesn't know about the hyper-accurate timer in the i686, so you
can't use it for any useful stats.
