I have tried this with the latest commits in both 11-STABLE and 12-CURRENT and
they have resulted in the same issue when linking my kernel. I'm unclear what
could be the cause, but since I am only seeing it on my i386 machines I figured
I would ask here.
Here's the relevant log snippet

And some relevant system information:

Any suggestions on how to debug/identify the issue here? I'm at a bit of a loss
for debugging kernel link errors :(
