Commit 03fa36df7e (package/avrdude: Switch to upstream)
unconditionally enabled linuxspi on the assumption that it is available
since linux-2.6.22.
However, avrdude unconditionally uses GPIO and includes linux/gpio.h,
which is only available since kernel 4.6 and:
3c702e9987
Add a Kconfig option, enabled by default for backward compatibility, to
drive whether to enable or disable SPI support.
Fixes:

Note: weirdly enough, GPIO support does not use linux/gpio.h; rather it
uses sysfs.
