Fix redefine error on some other version build environment.
|
Note that this header is part of LWIP, so this fix is likely to go missing at the time of the next SDK+LWIP upgrade. |

I have another (not good) idea, check the environment in Makefile and define in CCFLAGS while using espressif's Lubuntu. The espressif's lubuntu environment defined COMPILE=gcc and windows XP environment defined lx106. |

This macro will cause EFAULT redefine error while compile in espressif's Lubuntu build environment and ai-thinker's build environment. So add #ifndef EFAULT to check it is more safe.
