You recently removed an instance of -DCMAKE_EXE_LINKER_FLAG for
-latomic, so that would have been OK to re-introduce one here for
-liconv.

However, this is not very future-proof, and it would be easy to miss
that should we need to introduce other conditional linker flags.

So, instead, I rewrote it like we already did for KODI_C_FLAGS.

Applied to master, thanks.

Regards,
Yann E. MORIN.
