ESP8266 how compile firmware with FS and Graphics libs?

@hungryforcodes there is few not critical (i think so) warnings about declaration variables.

libs/network/esp8266/network_esp8266.c: In function 'esp8266_dumpSocketData':
libs/network/esp8266/network_esp8266.c:198:9: warning: variable 'stateMsg' set but not used [-Wunused-but-set-variable]
   char *stateMsg;
         ^
libs/network/esp8266/network_esp8266.c:182:9: warning: variable 'creationTypeMsg' set but not used [-Wunused-but-set-variable]
   char *creationTypeMsg;
         ^

and this

libs/network/esp8266/network_esp8266.c: At top level:
cc1: warning: unrecognized command line option "-Wno-float-conversion" [enabled by default]
cc1: warning: unrecognized command line option "-Wno-discarded-qualifiers" [enabled by default]
