Subject[RFC PATCH 3/3] x86/vdso: Add build salt to the vDSO
Date

The vDSO is linked separately from the kernel and modules. Ensure it picks
up the comment section, if available.

Signed-off-by: Laura Abbott <labbott@redhat.com>

I only added x86 in this series because that's my primary interest.
Other arches could easily follow suit if they care.
