Ah, that platform is not even supported...

Unfortunately, using LLDB for debugging Emacs means you won't be able
to use the commands defined in src/.gdbinit, which makes examining
Lisp data very inconvenient, to say the least. 
Yeah, to say the least :-).
Unless, that is, you
or someone else rewrites those commands in some script LLDB supports;
no one has done that yet, AFAIK.
Looks like that.  I couldn't find anything on the web either.  

I see LDB has Python scripting.  Maybe it's not so hard after all, then.
