The information is all there, it just has to be used.

But maybe the real problem is located in

./gcc/config/avr/elf.h:

#undef PREFERRED_DEBUGGING_TYPE
#define PREFERRED_DEBUGGING_TYPE DBX_DEBUG

so that is does not suffice to specify -g to get DWARF.
I copied these lines above from avr.h in order to have no functional 
change when I cleaned up the elf code and included ./gcc/config/elfos.h 
which reads:

/* The GNU tools operate better with dwarf2, and it is required by some
   psABI's.  Since we don't have any native tools to be compatible with,
   default to dwarf2.  */

#ifndef PREFERRED_DEBUGGING_TYPE
#define PREFERRED_DEBUGGING_TYPE DWARF2_DEBUG
#endif
