There is probably a way to tell where to load the libraries from, and
where to compile them.

By default, each compiler compiles to
~/.cache/common-lisp/$compiler_name-$compiler_version.

This is what ECL should do here.  The ASDF configuration should be so
that it does not change this  behaviour.

If you can't figure it out I can give it a shot.  Otherwise let's ask
the ASDF people.

Cheers!
