This add supports for the newer DF_BIND_NOW and DF_1_NOW flags. These are used instead of DT_BIND_NOW when linking with gold. Also fixed the order of checks, now it reports "No RELRO" when BIND_NOW is present but GNU_RELRO is not (in which case the bindings are done at start but they will not be marked as read-only).
