I am working on patch series to add an install target to the
main kernel makefile, so these tests can be built and installed
on a target just like we do with kernel and modules. I hope to
get this in 3.19 or definitely into 3.20

This probably will help address the problem you are seeing.
Install target is needed for qemu type environments as well.

thanks,
