* bfd-in2.h, archures.c (bfd_mach_h8300[h]): new defines.
* coff-h8300.c: More addressing modes. * coffcode.h (coff_set_arch_mach_hook): Cope with H8300 magic number. * cpu-h8300.c: Removed disassemble stuff. (h8300_scan): Recognise H8/300H name. (compatible): New function. * reloc16.c (bfd_coff_reloc16_get_relocated_sec): Cope with more addressing modes.
