#     powerpc/vdso: Make sure vdso_wrapper.o is rebuilt everytime vdso.so is rebuilt
#     
#     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.
#
