It is  necessary.  When you fix bug #14241 you have defined eeprom_is_ready 
macro in eeprom.h as:

#if defined(DOXYGEN)
# define eeprom_is_ready()
#elif defined(EEWE)
# define eeprom_is_ready() bit_is_clear(EECR, EEWE)
#elif defined(EEPE)
# define eeprom_is_ready() bit_is_clear(EECR, EEPE)
#else
# error "No write enable bit known for this device's EEPROM."
#endif

But the at86rf401  device has no bit EEWE or EEPE in sfr EECR, but has bit 
EEL in sfr DEECR therefore there a error  "No write enable bit known for 
this device's EEPROM." is generated. eeprom_is_ready macro should be defined 
as:

#if defined(DOXYGEN)
# define eeprom_is_ready()
#elif defined(EEWE)
# define eeprom_is_ready() bit_is_clear(EECR, EEWE)
#elif defined(EEPE)
# define eeprom_is_ready() bit_is_clear(EECR, EEPE)
#elif defined(DEECR) && defined(EEL)
# define eeprom_is_ready() bit_is_clear(DEECR, EEL)
#else
# error "No write enable bit known for this device's EEPROM."
#endif
