According to the output of avr-as --help, it only supports generating
DWARF-2. Thus, --enable-debug-info=dwarf-4 means DWARF-4 for the
compiler, and DWARF-2 for the assembly files.
However, for assembly source files, the generated debug info is very
limited anyway (I guess, to just the source line numbers), so there's
no practical difference between both DWARF versions for them.
