Adafruit FONA 3G and strstr_P not declared

Basic Infos

Hardware

Hardware: Adafruit Feather Huzzah (?ESP-12?) Core Version: I've tried all versions. Currently using 2.1.0-rc2

Description

I'm trying to use the Adafruit Feather Huzzah and the Adafruit FONA 3G (European version) in the same project.

I'm using the Adafruit Fona Library. And my sketch is based on a super stripped down version of the FONAtest example.

The FONA 3G library is not ported to ESP8266 and thus I made the following change:

Correction in this file: Adafruit_Fona/includes/platform/FONAPlatStd.h

//#include <avr/pgmspace.h>

#ifdef __AVR
#include <avr/pgmspace.h>
#elif defined(ESP8266)
#include <pgmspace.h>
#endif

When compiling I get the following error:

Arduino/libraries/Adafruit_FONA/includes/platform/FONAPlatStd.h:72:53: error: 'strstr_P' was not declared in this scope
 #define prog_char_strstr(a, b)     strstr_P((a), (b))

The sketch compiles, if I uncomment this line in the same file:

//#define prog_char_strstr(a, b)                    strstr_P((a), (b))

but then it keeps on crashing like this (print from terminal):

I have pinpointed the crash to this section in the Adafruit_FONA.cpp file:

  mySerial->println("ATI");
  readline(500, true);

  DEBUG_PRINT (F("\t<--- ")); DEBUG_PRINTLN(replybuffer);

  if (prog_char_strstr(replybuffer, (prog_char *)F("SIM808 R14")) != 0) {
    _type = FONA808_V2;
  } else if (prog_char_strstr(replybuffer, (prog_char *)F("SIM808 R13")) != 0) {
    _type = FONA808_V1;
  } else if (prog_char_strstr(replybuffer, (prog_char *)F("SIM800 R13")) != 0) {
    _type = FONA800L;
  } else if (prog_char_strstr(replybuffer, (prog_char *)F("SIMCOM_SIM5320A")) != 0) {
    _type = FONA3G_A;
  } else if (prog_char_strstr(replybuffer, (prog_char *)F("SIMCOM_SIM5320E")) != 0) {
    _type = FONA3G_E;
  }

The program crashes when calling the prog_char_strstr() function which I uncommented in the FONAPlatStd.h...

I am very confused as to why there is no strstr_P() function defined? By searching for several hours all over the internet I've found this ESP8266 library which seems to have this function defined.

I would be tremendously grateful if somebody could please point me in the right direction on how to solve this? Thank you!

For your information:

The boards are working properly in seperate projects (One project is Huzzah + ADXL345. The other project is Ardunio Duemilanove + FONA 3G).
I don't think this is a power issee as I've tried all kinds of setups. The Huzzah is powered from USB but I've also connected a 3,7V 2500 mAh battery. The same thing goes for the FONA 3G. I've also tried to use the bat out with a voltage regulator. Same thing.
