Add support GBZ80 and Z80N

Fix COFF linker test failures

I have no idea how to fix ld-elf/eh5 test failure. It is new test which was
enabled when I enable DWARF generation for Z80 target.

There is part of log:
regexp "^0+01(58|70) 0+0014 0+01(5c|74) FDE cie=0+0000 pc=.*$"
line   "00000158 00000010 00000000 CIE"

regexp "^  DW_CFA_advance_loc: 4 to .*$"
line   "  Version:               1"

regexp "^  DW_CFA_def_cfa: r0(.*) ofs 16$"
line   "  Augmentation:          "zR""

regexp "^  DW_CFA_nop$"
line   "  Code alignment factor: 1"

regexp "^  DW_CFA_nop$"
line   "  Data alignment factor: -1"

regexp "^  DW_CFA_nop$"
line   "  Return address column: 7"

regexp "^0+01(70|88) 0+0014 0+0(01c|148|15c) FDE cie=0+0(02c|030|170) pc=.*$"
line   "  Augmentation data:     0b"

regexp "^  DW_CFA_advance_loc: 4 to .*$"
line   "  DW_CFA_nop"

regexp "^  DW_CFA_def_cfa: r0(.*) ofs 16$"
line   "  DW_CFA_nop"
...
I have no expirience in DWARF. Can somebody helps me?
