Not at all, min_kver is runtime check, which could solve the latter
problem.

For this you can either:

* Add a configure check for syscfs()

* Add a fallback syscall definition to header include/lapi/

Fallback definition is preferable solution since with that the test will
still work on old userspace with new kernel.
