# binary-distribution of SBCL, or MSAN depending on the build target's config.
# But we don't really want that! editcore.lisp is capable of operating on any
# SBCL core and executing in any SBCL. So this should always prefer non-msan,
# but that's infeasible because lisp/sbcl/binary-distribution:BUILD chooses
# for you which subdirectory you get, and you can't pick both.
