-This works around the problem of TRK overshooting line-wise stepping by a few
-instructions. This is not a gdb problem, but a TRK problem, but currently
-easier to workaround on the gdb side. It's sufficient to apply for the
-arm-none-symbianelf targeted gdbs only as TRK is the only probe known to have
