Kernel interface changed with kernel 4.19, it does not accept raw GPIO
numbers any more. Deactivate these drivers on kernel 4.19 for now.

The build system already defines KERNEL_CROSS which defaults to TARGET_CROSS.
Make use of this variable for kernel makefiles.

This fixes this section mismatch warning:
The function spi_gpio_custom_get_slave_cs() references
the variable __initdata bus_nump.
This is often because spi_gpio_custom_get_slave_cs lacks a __initdata
annotation or the annotation of bus_nump is wrong.

The package makes it possible to create custom SPI
buses via GPIO lines.
This module is based on i2c-gpio-custom and allows to
configure an SPI bus via GPIO lines and expose it to
userspace without rebuilding the kernel. This is maily
intended to connect microcontrollers and other simple
SPI devices without making an ad-hoc kernel driver.
