Delete the remaining ROM monitor targets
Ref: https://sourceware.org/ml/gdb/2015-07/msg00011.html
All of these targets use gdb/monitor.c, which has bit rotted
years ago (I'd guess around ~6), and nobody seems to
have noticed:
| target | source |
|----------------+----------------------|
| target dbug | gdb/dbug-rom.c |
| target picobug | gdb/microblaze-rom.c |
| target dink32 | gdb/dink32-rom.c |
| target m32r | gdb/m32r-rom.c |
| target mon2000 | gdb/m32r-rom.c |
| target ppcbug | gdb/ppcbug-rom.c |
This deletes them, along with finally removing monitor.c.
A manual update will be done separately.
