I would change '$spadroot' so that we have '$spadroot' in Boot
and |$spadroot| in Lisp.  Current use was fine when '$spadroot'
was limited to small ghetto, but it is better to avoid
spadroot/SPADROOT irregularity when usig it in more places.

Concerning your motivation, IMO when using FriCAS FRICAS
environment variable should be defined and be an absolute path.
But if you want the change, then go on.
