Try to strace scripts/mod/mk_elfconfig to see why it is producing
that error message:

   scripts/mod/mk_elfconfig < scripts/mod/empty.o > scripts/mod/elfconfig.h
Error: input truncated

I guess that the empty.o file is not in the expected format.
Who owns that stuff, anyway?

You should probably post the empty.o file so that interested parties can
try to debug the problem.

I built the kernel just fine with the .config file that you posted.
