Well, it is not possible to get rid of backend-specific options,
because the prompts and help text of those options are not the same, as
they don't mean the same thing. For internal backend, the wchar option
is "I want the wchar support in the toolchain that you will generate",
while for the external backend, the wchar option is "Does the external
toolchain you're giving me has wchar support". That's the very reason
why we have per-backend visible options that select common hidden
options. Does that make sense?

Thanks for the review!
