bed->need_finish_dynamic_ifunc_symbol is unacceptable in my opinion.

Comment #3 says the only difference between good and bad binaries was a
.rela.plt relocation.  That would seem to indicate that the relocation is being
written once with the "good" symbol, then overwritten with the "bad" one, when,
as you claim, elf_backend_finish_dynamic_symbol is being called unexpectedly. 
But that means you must have other bugs, since the "bad" symbol must have
plt.offset != -1, which indicates it has a plt entry at the same location as the
"good" symbol!

I think you are just papering over real bugs by wanting changes to the set of
symbols for which elf_backend_finish_dynamic_symbol is called.
