procfs appears to be broken when debugging on multi-processor
machines. So enable software single stepping in order to avoid
using the procfs interface to do next/step operations, using
internal breakpoints instead.
* infrun.c (handle_inferior_event): Readjust the stop_pc by
DECR_PC_AFTER_BREAK when hitting a single step breakpoint, to
make this pc address equal to the value it would have if the
system stepping capability was used. Also set a new flag used
to ensure that we don't readjust the PC one more time later.
* breakpoint.c (bpstat_stop_status): Do not adjust the PC
address by DECR_PC_AFTER_BREAK when software single step is
in use for this architecture, as this has already been taken
care of in handle_inferior_event().

breakpoint has been hit when stepping onto a breakpoint.
