The structured information in .opt files is a lot more than just help
text, and is only likely to get more complicated over time (hence plugins
being a more likely way such information might be provided than specs).

What about a generic name such as -fextension- (or both -fextension- and
-mextension-) for options that GCC itself will ignore, if -mbsp= is
considered inappropriate? I'd prefer that to delimiting such options with
--start-specs and --end-specs.
