OK I see it now, only happens on x86.
It looks like it's coming in via kbuild. Though I can only see it being set in arch/x86/Makefile.um, and I don't know why that is being sourced. But it must be.
So this is another symptom of running via the top-level Makefile rather than directly.
I'll try and find a fix.
