Are there "no" versions of these options? In gold, once any of these
options is set, it can't be unset.
(Nevertheless, if there were a way to unset any of them, gold only
checks the final state of the options -- it wouldn't complain if you
had, e.g., "--static --shared --nostatic". HJ's patch appears to do it
this way as well; if there were a --nostatic, it should set
seen_static to FALSE, and you wouldn't get an error.)
