It looks like "$GUIX_ENVIRONMENT/etc" does not get added to
XDG_CONFIG_DIRS in an ad-hoc environment when sbcl is not in the list
of ad-hoc packages, which is why it fails to find some Lisp libraries.

In other words, this works:

  guix environment --ad-hoc sbcl sbcl-cl-str --
    sbcl --eval '(require :asdf)' --eval '(asdf:load-system "str")'

But this doesn't work:

  guix environment --ad-hoc sbcl-cl-str --
    sbcl --eval '(require :asdf)' --eval '(asdf:load-system "str")'
