I think the "|| COMPILE_TEST" might just be a copy 'n paste'ism (in fact I may even have been guilty off propagating it in reviews when checking for inconsistencies). AFAICT nothing will inhibit setting GPIOLIB so allyes- and allmodconfig builds will always end up with GPIOLIB enabled. If we are happy to select it then I think that is enough! Daniel.
