Subject: [PATCH 0/3] vdso: Always reject undefined references in during
 linking

Instead of using a custom script to detect and fail on undefined
references, use --no-undefined for all VDSO linker invocations.

Drop the now unused checkundef.sh scripts.

These patches can be picked up by the architecture maintainers.
