This implements cross-build for "make release", moving the build into a container. This way we can support arm, arm64, ppc, and whatnot. * script/seccomp.sh: separate out of script/release.sh, amend to support cross-compile and save needed environment variables to a file. * Dockerfile: add installing libseccomp from source, as this is needed for release builds. * script/release.sh: amend to support more architectures in addition to the native build. Additional arches can be added by specifying "-a <arch>" argument (can be specified multiple times), or "make RELEASE_ARGS="-a arm64" release" if called via make. All supported architectures can be enabled via "make releaseall". * Makefile: move "release" target to "localrelease", add "release" and "releaseall" targets to build via the Dockerfile. This is done because most distros (including Fedora and openSUSE) lack cross-glibc, which is needed to cross-compile libseccomp. * Makefile: remove 'cross' and 'localcross' targets, as this is now done by the release script. * .github/workflows/validate.yum: amend the release CI job to cross-build for supported architectures, remove cross job.
