Hi Alan,

   Have you seen this bug report:

>             Summary: Missing weak symbols in kernel modules on ppc64el

> Quite a few symbols in kernel modules on ppc64el are dropped after upgrading

> binutils 2.25.  This in turn completely breaks module loading on ppc64el

It seems that the cause of this was the patch for PR 4317:

   https://sourceware.org/bugzilla/show_bug.cgi?id=4317

Perhaps we need to allow some targets to require that undefined locals 
are preserved ?

Cheers
   Nick
