What kbuild does is a very basic link of a number of .o files.
Why this suddenly breaks I do not fully understand and I see no obvious
way to fix it in kbuild.
And browsing arch/ppc/kernel/vmlinux.lds.S I see no special handling of .opd.
Puzzeled?
I'm not sure how to deal with this one. Would prefer to say that this is
a binutils bug so fix it there but then I like to provide a workaround
for those with faulty toolchains.
I could put the link and the additional modpost check inside a
CONFIG_SOMETHING....
