Quicklisp does not look at XDG environment variables. The intent is that
if no sufficiently-new ASDF is already loaded, it will try to compile to
a fasl file in ~/quicklisp/cache/asdf-fasls/<hash>/.

I was going to suggest loading a sufficiently new ASDF before trying to
load the quicklisp/setup.lisp file.

However, now that I look at the Quicklisp setup code, I see that it
*unconditionally* does (ensure-directories-exist ...) on the asdf fasl
cache directory, even though it should only be done if Quicklisp needs
to compile its own ASDF.

I think one option is to preload the asdf-fasl cache and put that in the
jar.

I'll open a Quicklisp issue for the unconditional fasl cache directory
creation problem and try to fix it soon.
