Makefile references to undefined CONFIG variables

just FYI, results from my latest tree scan -- references from
Makefiles to CONFIG vars that don't seem to exist:

===== HAVE_GPIO_LIB ===== ./arch/mips/pmc-sierra/msp71xx/Makefile:obj-$(CONFIG_HAVE_GPIO_LIB) += gpio.o gpio_extended.o
===== MSPETH ===== ./arch/mips/pmc-sierra/msp71xx/Makefile:obj-$(CONFIG_MSPETH) += msp_eth.o
===== USB_MSP71XX ===== ./arch/mips/pmc-sierra/msp71xx/Makefile:obj-$(CONFIG_USB_MSP71XX) += msp_usb.o
