Well, it's probably not a big deal, since normally people would ask for
this, and one more library is either (1) not used if it is static (no
functions needed during the link), or (2) just some entry in a dynamic
table somewhere.

However, sorry I misunderstood the purpose of the check.  It's also fine
in this case to do that, I guess with some comment, as iconv is only
needed by linux-low, which is only going to be used on linux hosts.
