Indeed. I think it's worthwhile to add CONFIG_* expansion for such "hard"
CONFIG symbols to make headers_install, cfr. the existing unifdef support.
We do such a hard work to improve asm-generic, so new architectures can
just use that, only to see early adaptors now having to migrate away from it
(e.g. OpenRISC suddenly gaining uapi/asm/posix_types.h).
Or is there another solution?
