Yes. When GPIOLIB is disabled, the build issue don't happen.
because include/linux/gpio/consumer.h implement the dummy function
for all gpio functions if CONFIG_GPIOLIB is disabled.

For correct operation of max3355, you should add the dependency
to the extcon-max3355.c driver. This driver use the GPIO library

COMPILE_TEST is used for just build test. You can see the detailed data[1].
