There's also an unfortunate interaction with MODULES_OVERRIDE="" in that
the local modules are built / installed. This breaks the workflow I've used
in the past of 'make reinstallkernel MODULES_OVERRIDE=""' to get just the
kernel reinstalled w/o messing with the modules that I know are fine and
don't want to change. Not a huge deal, but still annoying.
