rdoff: disable broken backend, document deprecation

Browse source 
The RDOFF backend has been broken since at least NASM 2.14, throwing
an immediate assert. Since only one person appears to have even
noticed, and fixing it properly looks like it would take quite a bit
of work, disable this back end and document its deprecation.
