gnu: stex-bootstrap: Guard against unsupported systems.
The current implementation of nix-system->chez-machine et al. is rather brittle and fails in unexpected ways. In the meantime while a better replacement is being built, prevent falsy return values from causing errors, such as a failing “guix pull”. See <https://issues.guix.gnu.org/54292>. * gnu/packages/chez.scm (stex-bootstrap)[maybe-compile]: Use and=> to only call chez-machine->threaded if nix-system->chez-machine returns a truthy value.
