Not all compression types can be detected in the seccomp sandbox, so we need to disable it. This requires either configuring makepkg to know the sandbox is available, or checking for file >= 5.38 in which the sandbox option is a no-op even when seccomp is disabled. - Requires autoconf-archive for autotools version compare macro. - meson version comparison could be made a lot simpler using meson-git.
