mips32: Preventing FORCE_FRAME_POINTER from being optimized away
In functions that modify sp, debug and unwind information should
be located by fp instead of sp, and the conversion is completed
through FORCE_FRAME_POINTER. With gcc -Os, FORCE_FRAME_POINTER is
optimized away, and the modified sp is still used, causing a
segmentation fault in the recvfrom().
Adding a meaningless assembly instruction to use the return value
of FORCE_FRAME_POINTER to prevent it from being deleted.
