--- Comment #5 from Nick Alcock <nick.alcock at oracle dot com> ---
This suggests that libctf.so has not had needed symbols from libiberty built
into it properly (and bsearch_r is not called on by anything else in ld, so ld
will fail). This is quite strange given that we are still linking -liberty in
even after that commit.

At any rate, I do not see this with binutils master, so it's quite likely that
the fixes for bug 27297 fixed this too (even if I have no immediate idea why it
happened in the first place). Could you try it and see? (If so, I guess I'll
have to backport this pile of commits to stable, even though I was hoping to
avoid doing so because it affects a lot of things other than just ld.)
