I also tried rebuilding script/mod/modpost, but it didn't solve my
problem. How did you rebuild it, and did you have to do modify

$ gcc modpost.c file2alias.c sumversion.c -o modpost

I did some debugging in modpost, and found in my case that in
parse_elf, hdr->e_shnum was always zero, which is clearly not correct
or good. readelf says, correctly, that...
