Subject: [PATCHv5 4/4] arm64: Add build salt to the vDSO
Date:   Tue,  3 Jul 2018 16:34:30 -0700

The vDSO needs to have a unique build id in a similar manner
to the kernel and modules. Use the build salt macro.

v5: I was previously focused on x86 only but since powerpc gave a patch,
I figured I would do arm64 since the changes were also fairly simple.
