It builds for me on Ubuntu.
It looks like your 32-bit build setup is broken. The line that's failing to compile is:
#include <time.h>
Are you missing 32-bit headers? This test *can't* be run as a 64-bit binary.
We could enable it to work as a 64-bit binary by merging this:
http://lkml.iu.edu/hypermail/linux/kernel/1407.1/03739.html
but it would still be nice to build the 32-bit version. I could try to rig up some makefile magic to skip building it if 32-bit headers are missing.
