Becase b4 eats a binaries:
https://gitlab.com/rth7680/qemu/-/tree/lu-vdso
Changes for v6:
* Revert build-vdso.sh and meson rules.
* Add update-linux-vdso makefile rule. Since this is run manually,
we no longer have a problem with docker images failing to update
and causing the normal build to fail.
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.
