Add the standard arc_debug_printf, but also arc_linux_debug_printf, arc_linux_nat_debug_printf and arc_newlib_debug_printf to match the prefixes currently used in the debug messages. gdb/ChangeLog: * arc-tdep.h (arc_debug_printf): New. * arc-tdep.c: Use arc_debug_printf. * arc-linux-nat.c (arc_linux_nat_debug_printf): Add and use. * arc-linux-tdep.c (arc_linux_debug_printf): Add and use. * arc-newlib-tdep.c (arc_newlib_debug_printf): Add and use.
