changed the implementation of the VDSO from a PowerPC specific one to the
generic C version.

Apparently executables built with Go before 1.17 implicitly relied on the fact
that the VDSO did not mangle r30, but with the generic C implementation it now
does. This leads to random crashes in Go executables.

This is fixed with https://go-review.googlesource.com/c/go/+/334410/1 and I
submitted this to our go1.16 package with
https://build.opensuse.org/request/show/907807.

However, all executables built with a compiler which doesn't include that will
not work on kernel >= 5.13. This probably affects containerized workloads as
well. So it might be useful to raise awareness of this issue.
