Changes for v5:
* Integrated cross-compile, via new build-vdso.sh and meson rules.
However, keep the binaries in the tree for hosts which do not
have all of the cross-compile machinery.
* Update our loongarch64 docker image to avoid a binutils bug.
Changes for v4:
* Force all vdso to have a single load segment.
This will prevent problems with varying host/guest page size.
* Tidy some of the assembly with macros.
* Implement loongarch, ppc, s390x.
Just in case the list eats a binary:
