<div>
<pre>When linking output that contains only ifunc relocations (e.g.
R_X86_64_IRELATIVE) we miss the the DT_PLTREL, DT_JMPREL, DT_PLTGOT,
DT_PLTRELSZ .dynamic entries.
There is a reproducer at <a href="https://kib.kiev.ua/kib/kernel.tar">https://kib.kiev.ua/kib/kernel.tar</a>. This is a patched
FreeBSD kernel using ifuncs.
We emit DT_PLTREL etc. only if InX::RelaPlt is not empty, but ifunc relocations
are stored in RelaIplt.</pre>
