The testptp.c program is the example for the PHC API.  It should
compile without any trouble.

Here is how I would do it, taking the beagle bone as an example:

	export ARCH=arm
	export CROSS_COMPILE=/opt/x-tools/gcc-linaro-arm-linux-gnueabihf-4.9-2014.09_linux/bin/arm-linux-gnueabihf-
	export KBUILD_OUTPUT=/home/richard/kernel/beagle
	# compile the kernel
	make
	# install the headers under ${KBUILD_OUTPUT}
	make headers_install
	# compile the test program
	make -C Documentation/ptp -f testptp.mk

Easy, right?

Thanks,
Richard
