This sounds harmless -- if you have the corresponding package installed
(which I remember you wrote).

AFAIK (but take with a grain of salt) the kernel needs those to know which
modules to load dynamically when it "sees" new hardware (mostly via the
udev mechanism) -- or when you, for example, request new features (e.g.
a new filesystem).

Hmm. This file is conspicuously missing in the list you gave above. On
my system there is one (and besides, your "modules.builtin.bin" has zero
bytes). I guess that it isn't being made during the kernel build process.
Duckducking around gives no clear picture -- some suggest just generating
an empty modules.builtin (with touch), but I have no idea whether this
gets you into hot water later.
You should take it to the list, instead of responding personally to
me, perhaps someone more knowledgeable than me would chime in?
