m68k: enable named sections for vasm generated objects. have a separate as_m68k_as_aout for a.out objects which doesn't have named sections. amiga and atari gas defaults to a.out, so have it default on these systems. finally enable section smartlinking for amiga and atari, which will be used with vasm assembler
