it enabled by default to avoid a regression in the science/orthanc unit
tests. Set USES=iconv whenever ICONV is enabled, rather than only when
ICU is disabled. With the default option settings, this will bring in
converters/iconv on FreeBSD 9, which will unbreak the failing unit tests
in science/orthanc. At least one of the ICONV or ICU options must be set.
Fix PR 198658 in the default case by setting
BJAM_ARGS+=-sICONV_PATH=${ICONV_PREFIX} whenever iconv support is enabled,
not only when ICU is disabled as was done in r398027 (before that was broken
by r398060 and fixed again in the ports framework by r398258).
Pet portlint.
