build regression from c153693: Simplify module TOC handling

Hi Alan,

Your patch for "powerpc: Simplify module TOC handling" is causing the
Fedora ppc64le to fail to build with depmod failures. Reverting the
commit fixes it for us on rawhide.

We're getting the out put below, full logs at [1]. Let me know if you
have any other queries.

Regards,
Peter
