Subject: powerpc: Add build salt to the vDSO
Origin: https://git.kernel.org/pub/scm/linux/kernel/git/masahiroy/linux-kbuild.git/commit?id=29f07b97416a95d28ee62e70fd91b44956d3c8ce
Bug-Debian: https://bugs.debian.org/872263

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