buildworld fail: ld: error: undefined symbol: test_no_kevents

Hi,

Building on aarch64/14-CURRENT fails with this error on my rpi4.
It failed on incremental build and tried a clean build today.

First failure was on "World build started on Sun May 29 00:25:17 UTC 2022".

This weekend it still fails (I'm building weekly in Jenkins).
