Error: undefined reference to `strncmp_P' when using ESP8266

[PotatoX]

The Arduino IDE generates a compile error when building for ESP8266. I will generate a pull request to fix. The issue is around the strncmp call when using the ESP8266 core. I am currently using 2.4.0-RC2. I was able to confirm the error persists with 2.4.0-RC1 as well.

Pull request #3 created to fix issue.

Turns out the arduino linker doesnt like the .c naming. Change shell.c to shell.cpp. Fixed.

Hello.

I compiled the code for ESP8266 a few months ago and it worked. I´ll check and find out if a better solution is available, since this code is also meant for ohter platforms that only have C compilers available.

Thank you.

I confirmed the issue with 2.4.0-RC2 and 2.4.0-RC2, the issue was not present back when i tested with esp8266 because the command strings where stored on RAM at that time. At this time 2.4.0 is out and this issue no longer persists
