[ Upstream commit 205f3991a273cac6008ef4db3d1c0dc54d14fb56 ]
There is currently no dependency for vdso*-wrap.S on vdso*.so, which means that
you can get a build that uses a stale vdso*-wrap.o.
In commit a5b8ca97fb, the file that includes the vdso.so was moved and renamed
from arch/arm64/kernel/vdso/vdso.S to arch/arm64/kernel/vdso-wrap.S, when this
happened the Makefile was not updated to force the dependcy on vdso.so.
Fixes: a5b8ca97fb ("arm64: do not descend to vdso directories twice")
