It turns out this breaks building powerpc lint kernels. It shakes out
like this... makeLINT.mk copies sys/conf/NOTES into the generated LINT
config (I guess on the theory that things documented in NOTES are
supported by all arches). So option NUMA is present on powerpc, but the
powerpc vmparam.h doesn't define VM_LEVEL_0_ORDER so the build fails.
(Mips also doesn't define that, but it has no lint kernel build at all
right now.)

It could be fixed in vm_domainset.c with:

-#ifdef NUMA
+#if defined(NUMA) && defined(VM_LEVEL_0_ORDER)

but there may be some better way to fix it, I don't know that much
about this stuff.
