[commit] Remove config/m68k/tm-monitor.h

["Ulrich Weigand" <uweigand at de dot ibm dot com>]

Hello,

this patch removes the last remaining m68k TM file, tm-monitor.h.
The file contained two definitions:

#define BELIEVE_PCC_PROMOTION 1
is superfluous anyway due to the 
  set_gdbarch_believe_pcc_promotion (gdbarch, 1);
call in m68k_gdbarch_init.

#define DECR_PC_AFTER_BREAK 0
*does* change the default behaviour of
  set_gdbarch_decr_pc_after_break (gdbarch, 2);
set in m68k_gdbarch_init.  That default is used for the Linux 
and *BSD targets.  The patch moves the call from m68k_gdbarch_init
to m68kbsd_init_abi and m68k_linux_init_abi.  Then, the #define
becomes superfluous as well.

The patch should not change the behaviour on any m68k target.

Tested by making sure m68k-elf, m68k-linux, and m68k-netbsd
cross-GDBs still build.

Committed to mainline.

Bye,
Ulrich


ChangeLog:

	* config/m68k/tm-monitor.h: Delete file.
