Prelink asks ld.so what the symbol resolves to.  Jack, have you tried
re-prelinking using a recent glibc?  The search order changed recently.

I'm really surprised by this report, since the DSOs generated during
the binutils testsuite are not prelinked.  It might be a bug in the
conflict resolution code in glibc but I can't see how that would
happen.
