The COFF converter is incompatible with DWARF-2 input, as the objcopy
code in binutils doesn't contain a DWARF parser.  Thus, you have to
decide whether you want DWARF-2 or COFF debugging information.  In the
latter case, you need to tell the compiler to generate stabs debugging
information (-gstabs), and then convert that to AVR-COFF.
