Bug#723977: missing symlink in /usr/share/common-lisp/systems

[Faré]

(Adding asdf-devel to the recipients — the problem is wrong
(asdf::default-source-registry) when XDG_DATA_DIRS is empty.)

Well, ASDF ought to have worked even in absence of XDG_DATA_DIRS,
and you discovered a genuine bug in ASDF. It turns out, split-string was not
designed to return correct results when passed either NIL or "", and
this caused ASDF to fail to treat the default properly for XDG_DATA_DIRS.

I've pushed a fix as ASDF 3.0.2.9, but that's a pretty bad bug you've
discovered,
which defeats the default configuration.

Robert: when do you instead to release 3.0.3 ? Otherwise, I could do a Debian
package for 3.0.2.9. (PS: I took the liberty of also committing my
load-systems* patch).
