commit 791f9e36599d94af5a76d3f74d04e16326761aae upstream.
Commit bce74491c300 ("powerpc/vdso: fix unnecessary rebuilds of vgettimeofday.o") moved vdso32_wrapper.o and vdso64_wrapper.o out of arch/powerpc/kernel/vdso[32/64]/ and removed the dependencies in the Makefile. This leads to the wrappers not being re-build hence the kernel embedding the old vdso library.
Add back missing dependencies to ensure vdso32_wrapper.o and vdso64_wrapper.o are rebuilt when vdso32.so.dbg and vdso64.so.dbg are changed.
