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. r~ Richard Henderson (19):
