I don't have any idea, but I can confirm that I have seen the same thing
in the past when switching kernels.

If you switch back to the -rt provider, do a cleanall, and then go back
to the standard linux-yocto .. it should go away.

Something is obviously remaining in the sysroot/manifest after the
switch, but figuring out what  is going on here is deeper into bitbake
than my expertise can handle :D
