This is the best approach right now.  I've done this for a couple
of...unsavory programs and it works okay.

One alternative would be to create a 32-bit profile, and set up
FHS-style symlinks for it (or a chroot).  I've been thinking about
adding a "--fhs" argument to `guix environment --container`, but it's
still very much in the "dreaming" phase.
