This patch adds the "RejectNegative" property to several options where
it doesn't make sense. These are either options of the form
"name=value" rather than an on/off switch, those that are already in a
"no-" form, or options that form a mutually-exclusive set.
Also, the fhelp, ftarget-help, and fversion options that do not take
arguments ignore the "-no" prefix so that even "-fno-help" (etc)
causes help to be printed instead of suppressing help output. Since that
behavior is not useful, I've added RejectNegative to those options as well.
