That file is the only one that does all that weird choice stuff btw.

It's an optional choice with the choice symbols source'd from a
separate file, containing non-symbol items and symbols that end up in
implicit submenus and aren't considered choice symbols.

It's as if it was written to make use of as much obscure Kconfig stuff
as possible. :P
