[PATCH 0/2] link vdso with linker

Kees Cook is working on series that adds --orphan-section=warn to arm,
arm64, and x86. I noticed that ppc vdso were still using cc-ldoption
for these which I removed. It seems this results in that flag being
silently dropped.

I'm very confident with the first patch, but the second needs closer
review around the error mentioned below the fold related to the .got
section.
