That machine has a version of GNU libiconv in that location with symbolic
links to /usr/local.  I can't prevent configure from finding the one in
/usr/local, but there is a bug if iconv is in /usr/local and there is
no explicit "--with" flag (apparently because of differences in the
default treatment of /usr/local/lib and /usr/local/include).

This setup was working fine until quite recently.
