I have a expression that checks for libiconv, but it will only detect
it if ldconfig is present, if the system doesn't have ldconfig
(NetBSD), libiconv will not be detected even if it is present:

which ldconfig 2>&1 >/dev/null && (ldconfig -p | grep -q libiconv &&
echo 'y' || echo 'n') || echo 'n'
