For what $ARCH?  GPIO menu says this:

config HAVE_GPIO_LIB
	bool
	help
	  Platforms select gpiolib if they use this infrastructure
	  for all their GPIOs, usually starting with ones integrated
	  into SOC processors.

and then the arch-es that select HAVE_GPIO_LIB are these:

./arch/powerpc/platforms/52xx/Kconfig:50:       select HAVE_GPIO_LIB
./arch/mips/Kconfig:803:        select HAVE_GPIO_LIB
./arch/avr32/Kconfig:90:        select HAVE_GPIO_LIB
./arch/avr32/Kconfig.orig:85:   select HAVE_GPIO_LIB
./arch/arm/Kconfig:257: select HAVE_GPIO_LIB
./arch/arm/Kconfig:396: select HAVE_GPIO_LIB
./arch/arm/Kconfig:426: select HAVE_GPIO_LIB
./arch/arm/Kconfig:466: select HAVE_GPIO_LIB
./arch/arm/Kconfig.orig:401:    select HAVE_GPIO_LIB

so are you using one of those arches?
