You can't probe to see if a single one works -- only pairs of them.
That's the real reason we do this checking so late.

There may be other situations in which the current logic fails and
cannot be made to work.  The failing case would be something like a
host that has a native iconv but no way at all to list the character
sets.  But even here, installing libiconv will work.
