spidev_test has further evolved after kernel version 3.15, which is the most recent version that could be built in this package. This change allows to build the latest version of spidev_test if the toolchain's kernel header version allows it. In this way, when building with a newer toolchain, we are able to benefit from the added functionality offered by the newest version of the tool.
