I suspect, the real problem is the failure to load the loop module.
Which either looks like a bug in your configuration or the kernel
missing that module.

Why should that not be a problem if modules.builtin is missing?

https://www.kernel.org/doc/Documentation/kbuild/kbuild.txt says, that
you really want that, if you don't want modprobe to not fail for builtin
modules.

Is loop builtin in your case?
