Change of tack: whenever you get somewhere you expect to see you .md
file, open the console window and type "list". What does that say?
Also, can you tell me what you do to reproduce the problem?
If you give me a target triple and a test procedure, I can try to
reproduce a working case here and use that to troubleshoot your
scenario. Did you say some variety of arm worked?

You should not need to specify -gdwarf-2 and -g3 (that I know). On most
targets, -g will default to outputting dwarf 2. Just to eliminate the
possibility (and I'm not saying that specifying both will do anything
wrong), try just using "-g" -- at least while we try to debug this.

That should not matter as long as the compiler (and assembler, if
assembly is involved) are outputting debug info. I suspect they are not,
but again, I don't know anything about gcc .md files or how they are used.
