Ok, then to be safe, how about this:

if test -z "$XDG_DATA_DIRS"; then
    XDG_DATA_DIRS="@datadir@"
elif ! echo "$XDG_DATA_DIRS" | grep -q '@datadir@'; then
    XDG_DATA_DIRS="@datadir@:$XDG_DATA_DIRS"
fi

Of course that doesn't handle the case where there's a component of
XDG_DATA_DIRS that contains @datadir@ as a substring.  Maybe -- grep -q -E
'(^|:)@datadir@(:|$)' -- or maybe that only works in perl.
