"step" is used to step past a line of source code. The $s packet tells
the target to step past a machine instruction. Apparently in this case,
the source code line corresponds to three machine instructions.

This is expected. GDB has to single-step past the one machine instruction
before re-inserting any breakpoints and continuing.
