  This was reported as a failure downstream due to not having commit
ee1ada1bdb8074de6e1bdc956ab19aef7b6a7872 ("elf: Rework exception
handling in the dynamic loader [BZ #25486]").  I think it makes sense to
clean this up further and make things more robust.

Tested on x86_64-linux-gnu.

Thanks,
Florian
