Add a bunch of other GCC '-f' options and ignore them. This covers every
such option I've been able to find in the wild in our build system.

Note that I haven't added test cases for this. I can do so if folks
want, but they're *really* boring considering that this is all generated
code to parse and ignore unsued options.
