We had a related issue and I have suggested Rolan to just drop
the implicit installation of vdso when we do a "make install".
It would still trigger if you did a make vdso_install but this is
very rare so here it would not matter.
The patch we discuss just drop the cdso_install dependency
in arch/x86/Makefile (likewise for powerpc).
